Very quirky and interesting apartment, with some good local info provided. However, if you have small children beware of them climbing up to the single beds unsupervised, the handrail at the top is very loose and could fall off if you pull on it.
Hot water only seems available some of the time, you might not get a hot shower all the time. Also when finding the apartment, you may have to carry your luggage quite a long way as taxis may not take you to the door - then there are a lot of stairs to climb. But don't let any of this put you off - we enjoyed our stay.
