My wife and I spent a short weekend at the Sherlock last week. The hotel's location is excellent, close to numerous restaurants, supermarkets and public transport.
Upon arrival we were warmly greeted at the front desk and told that we had been upgraded to an executive class suite.
We parked our suitcase in the room and immediately left to shop in Oxford street which is a short ten minute walk away.
Upon our return, we discovered that the room had two single beds put together instead of a double bed and unfortunately the heating wasn't working.
The nice lady at reception immediately transferred us to a very nice room, with double bed and heating and we settled down nicely.
In short :
Service at reception is very efficient.
Their assistance and earnest understanding were second to none, as they honestly did their utmost to make our stay as enjoyable as possible.
Concierge - chapeau ! Highly efficient in restaurant recommendations, transportation arrangments and just nice young men who greet you nicely when you open the hotel door.
Rooms - the executive grade room that we reserved was clean and spacious well equipped with bath robes, slippers, safe, mini bar, sat tv and Internet. Lovely.
Breakfast - a downside to the hotel experience. Even though the breakfast is value for money, it could be improved. Coffee was bad, very bad. Pastries had dried out under the heating lamp and as result were very dry and greasy. Desite the nice selection of food, I personally think that more fresh vegetables could have been in order. I also didn't understand why I had to pay for fried eggs instead of the standard pale and watery scrambled eggs and for two sausages that on one day were served freely as part of their special continental breakfast, whereas the next day became a la carte - there is no way that anyone should have to pay 6 pounds sterling for the luxury of eating two sausages for breakfast.
None the less, the slightly disappointing breakfast did nothing to diminish our overall satisfaction at the Sherlock Holmes hotel and we definately recommend this establishment !
Thank you

Even if I don't stay here I try and eat here, today popped in for lunch at the bar and as always it was excellent. Staff are always very attentive.

Stayed at the Sherlock Holmes hotel for one night only (late January 2012), and didn't have time to look it up much before booking. I got it at a discounted price, and saw that the location seemed convenient for our stay. And so it was: only a few stops with the tube if you are coming from Heathrow Express (change at Paddington), and few minutes walk from Baker St. tube station. The room we got was very spacious, and everything was nice and clean, interiour very "standard modern hotel" but with small details themed towards the Sherlock name of the hotel. The staff was friendly and polite, without feeling intrusive or too pushy. The elevator worked a bit slowly more often than not, and it might be a bit hassling to enter the hotel if you're dragging a lot of baggage as the doors could feel heavy. The room was very warm when we arrived, and my boyfriend didn't read the instructions, so when he thought he was going to make it better by turning some ventilation on, more heat came on instead. We had to sleep with the windows open, but as our room faced a quiet back street we weren't bothered with noise during the night. The main road in front of the hotel didn't seem that busy in the evening either, though.
We didn't have the time to try neither the restaurant nor the bar.
All in all, I was pleasantly surprised, and would still have thought it worth the price if we'd paid the normal rate of about £130 as well.

I stayed here with a hen party for one night.

The location of this hotel is brilliant, very close to Baker Street tube and easy to get to Oxford st etc and other London attractions.

The room was lovely, was supposed to be a twin room but the beds were still together, a bit of furniture moving soon sorted that out. Room was a nice size though with plenty of storage space.

The bathroom was tiny, and had a really strange glass door which wasn't all frosted, needless to say this made using it interesting, the door also didn't close very well. Possibly would have been okay if staying as part of a couple.

The breakfast was nice, and there was lots to choose from, thought it was odd that there wasn't any bacon though and just sausages!

The staff were really nice and were very accommodating especally at breakfast time when our group was split up over 2 tables, they moved us about as soon as tables became free.

Over all a nice stay in a nice hotel.
