Cozy place on the heart of Trastevere. Nice decoration, stylish, with a cool private terrace to chill out on the rooftop. Communication with Mario, the host, was excellent. The building is a bit old, but the apartment has many renovated facilities, specially the bath it's pretty new.
The only bad side is the Wifi speed, at least when I was there, if you plan to work from home, you will better find a coffee shop on the area (for example Baylon Cafe, 5 mins away).
