We had a nice experince staying with Gabriel and Federico. Despite arriving quite late, they gave us a very friendly welcome. The appartment was very clean and cozy, we had no problem with all the amenities. Also noteworthy is the area we were living in - Trastevere is just busting with cool places suitable for having fun, sight seeing and enjoying the best of italian cuisine. Moreover, it was just 20 minutes away from the very city centre (on foot!). I would definitely recommend staying with Federico and Gabriel
