Communication with Alberto and his wife via mobile was very easy and they responded quickly. His wife welcomed us into the apartment and showed us around. The apartment is nicely located, with pizzeria on the doorstep and a few minutes walk to the center of the city.
The neighborhood is the "nightlife" area of Rome - so there is a lot going on in the streets in the evenings. Unless you go to bed very early, this shouldn't bother you. During the day you can discover some small stores, at night mainly the restaurants and bars.
The apartment is just as charming as in the pictures, with nice views of the street & small kitchen. Unfortunately, sharp knives and a working bialetti were missing - but we were able to buy these for a few euros and Alberto even brought us his own bialetti! He is super friendly and helpful and communication worked well.
We felt very comfortable and will be happy to visit again.
