We had a good stay at Eva's place. The top notch is the location, in the middle of well animated Trastevere, but still in a very quiet small street. The apartment is clean and big, although it looks quite old and a bit worn out. Since we were there mainly for sleeping, that's ok. The communication with Eva was easy and fast, although we didn't meet her in person. We recommend the apartment mainly for its amazing location.
Note: Nothing to do with the apartment itself, but be aware about the public transportation (busses) in Rome, in particular the bus line H which brings you directly from the main train station Termini to Trastevere "Giachino Belli" (and back). We didn't meet any issue from the main station Termini to Trastevere upon arrival, but then we never get it back the other way, from Trastevere. It just got delayed and delayed. We waited around 40 minutes, and finally decided to give up and took another one (Line 8), changed in Piazza Venezzia, and got another bus to the train station. So foresee enough time if you have to catch a train while using busses. Busses are not reliable at all.
