Our stay in the apartment was more that excellent. It's just the like pictures, and when one enters it, one falls in love. It's spacious and really sparkling clean. The kitchen is well-equipped and very suitable for cooking meals. The living room is naturally lighted and nicely decorated (so are the rooms) which makes it tempting to set in for coffee/drinks.
Our host, Giovanni, was of great help. He welcomed us when we first arrived, and sat with us when we asked for info and local recommendations. Furthermore, he was always available and very responsive via messages.
The apartment is located in a very quiet nieghborhood, it is safe and the building has a guard, everything is locked and only residents can go in. Thus it is very suitable for families.
However, we felt that the area was a bit secluded; there is a couple of small grocery stores and they close at around 20:00, so we had to make sure to buy things at day or bring them with us late at night from the city center. Luckily the metro station is a 3-minutes walk and this helped us a lot (in 5 min you can reach the center via the metro).
It was a pleasant stay, the apartment is great and its design is very delightful. We recommend it!
