Very pretty and stylish apartment, in a great location, probably best suited to the younger traveller. Great value if young and fit and going to be out of the apartment most of the time.
Take the warning about the stairs very seriously! It's a stone spiral staircase so feels more like 8 flights than 4. Don't expect a view from the 'terrace', it looks out onto an enclosed courtyard.
I recommend earplugs and sleep mask if a light sleeper.
