Overall we had a wonderful time in this apartment. It is a large space that is well decorated. The internet worked well for two of us working there all week.
There were, however, dowsides. We were given two keys to get into the building; one only worked when giggled in a complex way that we had to figure out ourselves, and the other one never worked. There is no A/C, I did not notice that in the description and it was a warm surprise. There was a lot of construction in the building, which made it loud all day while we were working. Then, even when there wasn't construction, the sound of cars or scooters flying down the narrow road was very loud. Especially since we had the windows open due to the heat. I imagine this noise is an issue anywhere in Quartieri Spagnoli, not just at this apartment.
So overall, there were some unpleasant surprises that were not necessarily the fault of this apartment or its owner, but future guests should be aware of.
