We stayed in Giulio’s apartment in November. The place was clean and for 4 people it would be perfect. After we booked the place we got joined by another couple of friends and we ended up being 6 in the apartment but as we mostly spent time outside, it was not an issue. Kitchen is sufficient if you don’t expect to do any big cooking there. Bathroom was small, but clean, there were no problems with hot water, only downside was that door on the shower let a lot of water out so we had to dry the floor after every showering.
Check in was smooth and location of the apartment is perfect, in walking distance to all major sights. Even though the area is quite lively in the evenings, we heard some noise from outside only on Friday and even that wasn’t that bad.
Overall, I would definitely recommend staying here.
