Apartment was exactly as described. The view is absolutely stunning. We didn't mind the small space as we only used it as sleeping quarters. Note: if you do have mobility issues this place could be a challenge. The elevator was small, could fit only 2 small people max. If you don't want to take the elevator the you'll have to huff 6 flights of stairs. The host is very clear about this though.
Had a great time in the flat and would totally stay again. The host was as accommodating as possible and was a pleasure to deal with.
