I've had a fair amount of travel so far across few countries in Europe, Australia and middle east. But it is the first time I felt I wanted to come online and write something about a hotel I stayed in. The customer service I experienced starting from the doormen to the front desk and everyone else was really different from all other hotel I've been to.
This hotel is in a great place, walk to the famous beer house shopping and really great room service and breakfast. Everyone is very friendly and cooperative.
Whole place is neat and tidy. Room services is very quick and they all are very eager to help in every possible way.

I have been using CGH for two years and last year (2011) I spent over 30 nights here. The staff are delightful and the rooms excellent - I always have a deluxe room for space to work, the smaller ones can be cramped - with beds that are sensational.

There are one or two drawbacks. Wifi is a cost option of £20 per day which drives me mad and breakfast is not included and can quickly add up. Although the food is very good.

Expensive but worth it.

Were it not for my new policy of marking down for not providing free WiFi for guests when you are paying top dollar and even Starbucks and Nero give it for free. Extremely annoying and petty for a hotel that is charging a hefty fee for a room to not through in Internet. Hopefully if enough people do this they will be incentivized to change it.

Don't get me wrong, it would normally get five stars from me, the rooms - though small - are well put together and very pleasant. The staff are very nice and helpful. And the guest drawing room with honesty bar is perhaps one of the most brilliant inventions of all time. We didn't really use it this time but we have in the past and it is, in a word, brilliant. That coupled with location make it one of the best hotels to stay in London.

There are a couple of downsides besides them charging for WiFi. The bathroom is quite small (and I have absolutely no idea how the steam thing was supposed to work). And they only have one key per room which is annoying when you are not attached at the hip with your roommate (we had to get creative). Also, the gym is tiny, as are the elevators. But I guess size constraints is the trade off for small and quirky in central London. One I'd gladly pay, especially if they fix the internet thing (I'll stop harping, I promise) and the keys thing.

I travel to London twice a year for work. Once I found the Covent Garden hotel, I decided never to stay anywhere else. First off, their location is ideal in my opinion for great shopping (SOHO, Covent Garden), fantastic dining, and the theater district, of course. Secondly, everything about the hotel is beautiful: amazing decor with each room sporting it's own unique look within a common designer. The service is -star, from the concierge to the desk staff to the housekeeping. I am a linen freak, so I especially appreciate the level of bedding and towels :)
If you are looking for a perfect spot to stay on business or as a visitor for sightseeing, I can't recommend Covent Garden Hotel enough. (PS - their sister hotel, SOHO, is fantastic, too. Highly recommend it as well. I just prefer the older charm of this building.)
