We stayed with 4 people at the flat and had a wonderful time. The flat has been renewed in December 2013 and has a modern-style with f.e. inbuilt WLAN loud speakers in the ceiling and a big bathroom with jacuzzi and steam-bath.
The flat is located in trastevere, just beside some nice bars (REC23) and restaurants (Pizzeria Reno, Nouvo Mondo) which are visited by romans and only a few tourists.
The host alessandra made everything possible, she gave us hints for sightseiing and restaurants.
Overall, nothing to regret. Everything was perfect!
