Pros:
The apartment overall was good - it was a fully furnished apartment with all amenities, and a nicely equipped/ fully functional kitchen. The washing machine was a great help as we'd been travelling quite a lot and were able to get some essential washing done!
The apartment is also close to several attractions, so easy to get out for sightseeing. A funicular goes right in front of the apartment door.
Cons:
The location can be a real problem for families - it is in a controlled area, so not all taxis go to the apartment door. In terms of walking, there is a really steep climb on one side, lots of steps on the other - tough if you have a pram or old people in your party...
Not very quiet - there was some late night noise in the street below and in the apartment complex (it was the weekend) but didn't last very long.
Neutral:
The black theme on the walls a little jarring, but one you get used to after a while.
Overall, a decent place to stay but would look for another, more family-friendly, place next time.
