I highly recommend staying at Claudia´s apartment, everything was just great! We loved Trastevere, especially the Caffè Trastevere di Ela Bar on the corner of the street where we had capuccinno and croissant every morning. It can be very loud in Trastevere, so we highly recommend to bring and use earplugs during the night, it helps a lot! The apartment was shared with 3 other guests, but they were very nice also. We loved that place, we would definitelly stay there again!
