Great place and cute location! Close to the kings cross station and to any local bars. You do have to walk up the stairs which is fine to me (NYC apts are all like that) I dealt with the air butler Jon and he was fantastic. He let my husband and I to check early since our flight landed earlier than check in time. Jon was able to meet with us to let us drop our bags and instructions to check in once the cleaners were done.
There was a couple of times I showered, it provided me cold water after 10 mins in the shower- not sure if it was normal but something to mention to the building manager. Overall I thoroughly enjoyed the stay!
