We stayed at that Rembrandt, the one across from the Al and Vic museum, and a couple of blocks away from Harrods. Now granted it was November, but we enjoyed it, the staff was so helpful and pleasant - but I do not know about AC, as we obviously would not have needed it in Nov. We walked and walked and rode the double decker buses and managed to see everything we wanted to. I think Anne is right it is now part of the Sarova group - but Pam its a nice place and very quaint, with lots of twin bedded rooms. :D :D Actually I think we wanted to stay at the Reubens Hotel, but it was booked and they referred us to the Rembrandt - I don't remember for sure, because the couple we were traveling with made the reservations. Try the Reuben Hotel also.
