We stayed in Sabrina's hostel in January. It's more like a hostel, you feel like in a hotel room with a shared kitchen. The location was good, close to Trastevere trainstation (close to Fiumicino!). The bed was very hard - some like it, some don't. Sabrina was very nice and the communication was great. Unfortunately the shower/use of water from the other guests was very loud, we couldn't sleep without ear plugs. Nevertheless, our stay was good and we recommend the hostel.
