Marriott Park Lane
Have been there a number of times and agree that it feels more like a boutique hotel. The rooms are quite small but nicely designed. Worth it to upgrade IMHO for a bit more space. We have always enjoyed the location which is really great for getting around London using bus or tube. We are going in August and opted for the Marriott at Grosvenor Square which will be our first try there. We thought about St Pancras because we love older rehabbed buildings but the location is not great. The do a very nice job at Park Lane with the club but it is small. We have always found the staff there to be very good.
