We stayed 5 nights in December right before Xmas. Coming from California we were a bit anxious about the cold weather that London was experiencing. It had even snowed. Thankfully the flat was cozy warm and even had a portable heater for the kitchen/bath area. The location is terrific and we were able to walk every where we wanted to go. Best feature of the place however is the size of the bedroom area. That was a real plus.
