Their listing indicates that there is no elevator, but (thankfully) there IS an elevator. Almost all rooms face the backside of another building, so if you want to see the sky, this place is not for you. There is no heat or AC, which didn't affect my stay (the weather was mild), but it would be tough to stay there in high winter or summer. I wouldn't. TV has no local channels, only streaming services IF you have your own accounts.
The kitchen is well-eqipped (except for lack of a dish towel). The bed and pillows were very comfortable. The location is very central and convenient for walking to many sights. Every staff member was helpful and friendly. I enjoyed my 3-night stay.
