Fabio is a great host, he's kind, responds in a few minutes and he helped us with everything we needed.
Apartment is on a great location: cca 2 mintes from store, wonderful gelateria and nice fruit store; cca 8 minutes from metro to center/Vatican/trainstation; cca 25 minutes to Colosseum by foot.
We felt save in this neighborhood, and Fabio helped us with anything we asked.
The room was cozy and clean - sheets and towels (lots of towels :D) smelt fresh and clean.
I saw some people are writing that lack of air conditioner bothers them, but I wouldn't agree. It was over 32 C while we were there, but a light breeze and a low moisture made it feel like it was much less. And during the night it is really cosy and much colder. Even if we had an air conditioner, we wouldn't have used it at all.
I would recommend this place for it's price to value ratio and for Fabio's kindness and hospitality.
