Me and my boyfriend we stayed at Liberas place. When we arrived, we had to wait aprox. 10 min. until her sister, Olga, showed up and luckily let us in. Unfortunately we didnt meet Libera herself. Olga stayed in the apartment, but actually we didnt see her a lot. But when we saw her, she was REALLY nice and helpful! She even recommended us a nice market and a restaurant!
The location of the apartment is PERFECT! The area of Trastevere is just the best location to stay. There are so many nice restaurants, bars, Piazzas and little streets. Really wonderfull! Besides that it is very close to the river and in walking distance of all important sights. We walked a lot and just rarely took a bus. It was definitely the best decision to stay there!
The apartment itself was also really nice. We didnt spend a lot time there and didnt use the kitchen/ living room. We actually just slept there, but that was perfect as well. The room is really spacious. You have enough place for your luggage and a big closet. The bathroom is beautiful and we were provided with enough towels. The bed is huge and really comfortable! The only thing is that sleeping with open windows is a little bit noisy. We did that one night and the others we closed the windows as it was better. But all in all I wouldnt call it a problem.

To summarize: we had a perfect stay in Rome, felt at home and would definitely recommend to stay at Liberas place! We loved it!
