Quite difficult in having to pick up the room key from the office which is 4 tube stations away from the room. Which must think about bring a large suitcase along the way, and the tube station at the office and at the room both do not have lifts. This means you have to carry your luggage up and down the tube. But the room building has a working lift. On the day of check-in, gas and heater problems cannot be used. But we were able to contact the office and they sent someone to slove the problems that night and there were no more problems. The room is spacious and has complete equipment as told.
