Private location, private entrance, very central. You can get to every major location with a 10/20 min walk (besides Villa Borghese and Piazza di Spagna, which it may take longer). Good restaurants around and two very good markets really close (Coop and Pam Local).
The house has every amenity I expected. As a plus, has 2 bathrooms, something not common in Europe.
Perfect for 4 people, and for kids also. Me and my wife stayed for 7 nights with our 5 and 2 year-old daughters and we had no problems with them. The apartment is not tiny, but also not big. The rooms are really big, but the living room/kitchen is not big. Since we only stayed there to sleep and to have breakfast (as you should, Rome is a wonderful city and has a great night life), that was not a problem for us.
Not good for people with disabilities though, since it has small stairs and the corridor floor is not leveled with the street.
Definitely recommend staying at Veronica’s!!
