We found The Levin on TripAdvisor. Two weeks before our trip, it suddenly rose to the top of the London rankings because reviews had just been posted. Apparently, it just re-opened around December 2007; it had been a different hotel previously. Since we booked last minute, we got a great deal.
Even without the excellent rate, this is a great hotel. I could see Harrods from my window, so it was only a 2-minute walk to the Knightsbridge tube. The rooms are a really nice size, especially for a London hotel, and they are beautifully outfitted: flat screen TV, Bose radio, marble bathroom, etc. I have not seen this before, but you get a card with your key that turns the electricity off when you remove it to go out for the day. What a brilliant way to save energy!
This hotel has a lot going for it. Being smack in the middle of Knightsbridge, it is convenient to shopping and dining, and just the walk up Basil Street is quite lovely. It's a quiet residential neighborhood, so you don't get a lot of city noise. The rooms are quite posh with decent storage space and, as I said before, I couldn't believe how spacious they were for an older London building. It is rare to have so much room to walk around; we didn't trip over the furniture or our suitcases! Bathroom is lovely and has nice toiletries; my only difficulty was trying to hang my towel back up on the rack, which appeared to be heated but which I could never get going. My kids were very impressed with the sinks! Full English breakfast was included in our room rate (and was very nice!), but even the Continental breakfast choices were lovely. Truly, this hotel offers a lot of value (in a lovely package) for the money, even at these current exchange rates for the American dollar.
I have a few suggestions regarding your stay. First, if you are a light sleeper, try to get a room above the first floor, where we stayed. I could hear a little noise from the lobby (but since there is no bar and the lobby is quite small, it was really minimal - I'm just a really light sleeper). Also, if you are a light sleeper, ask for a room that doesn't overlook Basil Street (again, this is a very mild comment - just some trucks presumably going to Harrods and picking up trash in the mornings).
Also, the front desk staff did not seem as knowledgeable about London or happenings as you might expect at a nice hotel. (This is not a tremendous surprise - the last time I stayed in Sloane Square at the now-renovated hotel there, their idea of a concierge was a young man with a phone book.) They seem to be new (as is the hotel) and they do have phone access to the concierge next door at the other property (The Capitol - a more-established hotel), but I was given the wrong information about the changing of the guard one day. If you know what you want to do in London, there is no problem, but I'm not sure that I would rely on them for ideas or little brochures as at some more tourist-oriented hotels. This being said, however, they are extremely eager to help and will use the computer at the desk to access the Internet and get you whatever information you require. They may simply need some time to learn more about the city.
Lastly, I just want to mention to travelers with families that ours seemed to be the only children in the hotel (our kids are 7 and 9). This was is in no way a problem, and they were treated well by the staff, especially by the breakfast staff (pots of hot chocolate were a nice treat). This is a nice hotel with lovely decorating that seems to cater to a sophisticated traveler, so if your kids are used to a more Disney-like atmosphere, this is not it. However, if your kids are seasoned travelers and know how to be quiet in the hallways and lobby, you will enjoy having a bit of extra space that these generous rooms offer.
Please consider that these above comments are quite mild and meant to be helpful to potential travelers, not critical.
All in all, we had a wonderful stay at The Levin and would certainly return.
