The location is just amazing! It's perfect to visit most of the city center just walking around. Not to mention the extreme vicinity to Trastevere, which is very nice to enjoy the night life.
The apartment is just as described. Not huge, but nicely sized for 2 people. Fabio (Rita's husband) welcomed us warmly, helped us to carry the luggages upstairs, and gave us all the necessary tips to enjoy our stay. There were quite a lot of things to eat for breakfast (croissant, cookies, yogurt, coffee, tea + an undefined amount of mono-portions of nutella, butter and jams). The cooking space allowed us to cook our own meals too, in those days we didn't have the strength to hit one of the many restaurants in the area.
