We enjoyed staying at this place very much. It's in a great location - a quiet neighborhood but still close to everything. The apartment is small (we had trouble finding space for two open suitcases on the floor in the bedroom) but very stylish and well-kept!
The elevator in the apartment is a curious detail, probably most useful for cyclists or parents with strollers. As others have mentioned - the elevator doesn't provide great sound insulation. So you can hear your neighbors in the same building quite well (pretty sure all other apartments are airbnbs or similar).
We would definitely stay at the apartment again when we come back to Girona!
