This is a pretty solid deal. The location can't be beat if you want to stay in the heart of London. Transportation was a breeze, both via train, hired car, and on foot. There is a ton to see and experience, all within walking distance. The building is well-maintained and safe, with a friendly and helpful concierge staff. Helen herself is fast to reply and take care of your concerns. The overall experience earned four stars. We would give five but for the amenities. The essentials are present and accessible, it's just that they could be more plentiful. The kitchen could be better outfitted, and even some small things like a coat rack, brighter lighting, and carpet runners or area rugs could make a big difference. It wasn't balcony weather when we were there, but the balcony is spacious and would be quite appealing in nicer weather.
