We've stayed at this apartment for 4 nights with our 2 kids (4 people altogether). The location of flat is great, very close to Sinoria and just behind Ufizzi. Just a little bit far from station, so if you travel with luggage better to take taxi.
Elisabetta was waiting in front of the door and greeted us warmly. As well, she left for us on the table some snacks, water and bottle of wine so there was no need to look for supermarket first day.
The flat is quite high located in an old building, so difficult to climb the steps with luggage (that's why I would not recommend for people with health problems).
It has 1 bedroom, 1 big living room+kitchen and bathroom. For family with 2 kids just enough. I would mention that sofa in living room has a very good mattress so it's comfortable to sleep.
Apartment was clean, linen and towels fresh, all equipment working and wi-fi connection good. Elisabetta provides detailed instruction in a special book how to use all equipment, waste collection point, keys usage etc. For cooking I found there everything needed except the kettle.
At night our kids slept well, but in the bedroom you can here neighbors and some of them used to talk loudly till 2am (as they spoke English, I suppose they were tourists - so no claims to Elisabetta, we were just not lucky).
As well, we used heating first night and apartment got warm very quickly. Generally, I am very satisfied with our stay in this apartment and would recommend it to couple or family with kids.
