We enjoyed our stay at the Malmaison Charterhouse Square very much. Staff was uniformly helpful and cheerful, our room on the 6th floor was quiet and comfortable (especially the not-too-soft, not-too-hard bed), and all the facilities were spotless and well appointed. We had a lovely dinner in the hotel restaurant as well. Lots of little extras, like tea- and coffee-making facilities, biscuits, and lovely toiletries, plus quirky decor details made the stay especially nice.
