I stayed here with my husband while we were both in London on business in February 2012. I should admit that I don't enjoy hotels and much prefer to stay in apartments where I can come and go as I please, have more space, cook my own meals and have greater independence. And normally have free wi-fi (the Hyatt charges 7GBP per hour or about 120GBP per week which is outrageous on top of what we're paying for the room).

So I approached the Churchill with some reservations. I needed a place to be able to work within the room, that was close to good public transport, close to central archives and libraries, and with a comfortable bed.

First, I have mixed feelings about the location of the Churchill. If you want a central business/Oxford St location then this might work for you. The hotel is located in Portman Square, a block from Marble Arch. That makes transport connections easy by both bus and tube. It's also close to Paddington, for access to Heathrow, and within 15 minutes (bus or taxi) to St James, Knightsbridge, Notting Hill and Oxford Circus. If you're after shopping then this is at the quiet end of Oxford St and it's about a 20 minute walk to Oxford Circus, and another 20 minute walk down Regent Street. If you're after character then I don't think Marylebone is great. I'm happier in precincts like Bayswater and Notting Hill, but you don't find big hotels there.

Secondly, I have mixed feelings about the rooms. The beds are very large (super king?) and the pillows are deep and fluffy. The decor is neutral. The bathroom is clean and modern but drives me nuts with its layout. Too many doors open (and close) onto each other and it begins to feel dangerous. Definitely inconvenient. The desk is well equipped for business travellers - there's a reasonably sized work table with international wall plugs for electrical devices (UK, US and Europe - not Australian). I don't get much creative vibe but it won't offend anyone. The lights are not well designed - you can't have just a bedside light on at night to read without having major ceiling lights on in the entry. Or perhaps that's just my room.

Thirdly, the service is excellent and deserves a major mention. This is the reason I would come back to the Churchill if I did. The housekeeping staff keep an eye on the room (sheets and towels) at least twice a day. We see them often in the corridors and they are absolutely gorgeously friendly but scrupulously professional. Door staff, room service and counter staff are equally as lovely. Extremely consistent across the hotel in the quality of service. The food in the restaurant is nice; the room service food has always been delicious and beautifully presented.

Business centre facilities, as you'd expect, are standard and over priced.

The hotel seems to lack lounge or bar facilities. It combines a restaurant and casual drinks/meals area in one space, which means there is no obvious place to crash with a laptop and coffee that isn't actually the restaurant itself. But there is a live pianist/vocalist most nights which everyone seems to appreciate.

If you're looking for entertainment, I found a cinema around the corner (Baker St) called 'Everyman' which is an independent chain that's well worth a try. It has two underground screens in small theaters. Each contains about 10 short rows of plush velvet chairs. The bar sells home made snacks like roasted nuts and hommus, wines and coffees, all of which can be taken into the cinema and set down on the small side tables positioned on the arm rests. Adult ticket prices around 12GBP.

All in all the Churchill is a decent hotel if this is the kind of venue you need.

We stayed at the Churchill when we were in London for a wedding. We found the staff very helpful in helping us plan our free time. The restaurant off the lobby was a great place to recoup before and after a hectic day. The location was perfect - not far from the underground and the shopping. I would definitely stay there again when returning to London.

Hubby and I spent one night at the Churchill. We arrived in London at 11am and walked to the hotel to drop off our overnight bag. We were warmly welcomed and informed that they had a room ready for us. Check in was quick and efficient and there was an offer to be shown to our room but we declined as we only had a small bag.
The room was at the back of the hotel with not a lot to look at but for one night we didn't really care. The room was smaller than I was expecting and the carpet and easy chair could really do with updating as both were showing some wear.
Bathroom is what you'd expect in a hotel - clean and plenty of white towels.
We were booked on a half board basis and went to dinner at 7.30pm - no reservations were required as the hotel was quiet.
On arrival at the restaurant we were shown to a table and given the a la carte and set menus. We were eagerly looking at the set menu as this is the one reception told us we would be having as half board option.
We chatted to our friends who had already arrived and they told us that there was a third menu specifically for half board. We were a little disappointed as this menu had much less options on it. But what the heck the stay was for free (our friend won a competition!).
The food was excellent, well presented and flavoursome.
Bedtime: the bed is very comfy and has a very warm duvet on it. We found the duvet too warm and found we were kicking it off and pulling it back on most of the night. Not the hotel's fault as they have to cater to the majority..
Breakfast: Plenty of variety - cold meats, pastries, cereal, fruit, yogurt, juices as well as the traditional full english. One thing they need to change here is the table at the top of the aisles at the back by the kitchen area, the waiters and guests have to get past you to reach the kitchen and bump into you all the time. If we had stayed another night there is no way I would sit there again.
Check out was quick and easy.
All in all it is a good base for the Oxford Street area and I would stay again.

Being a Hyatt Diamond, we reserved a suite on points in the Hyatt Churchill, a great property with friendly staff. When we checked in with our baby, we saw that we received the smallest suite I ever saw and wanted to leave to our other usual Hotel in London. I also made a call to another Hyatt, where I knew the MD and rapidly all was solved and we received for free the Presidential Suite which for London properties is rather nice and large.The bed was so comfortable and the bathroom was a room in it self. Big and pleasant and a wonderful rain shower.From then on the service level was fantastic. The Executive Lounge was just so pleasant with the many nationalities there and the atmosphere was so relaxing at this property, that we exteded one day. Being less than 1 minute away from Oxford street, I would say that the cleanliness of the room, the great breakfast and the fantastic staff really make up for the price you would pay there. Definitely my Hotel for the future in London shall I keep my Diamond status.
