I stayed at Sergio's place for 2 weeks and had an excellent experience. The apartment is in a new building with modern amenities. It is a very comfortable and clean one bedroom with some nice design touches that quickly made me feel at home. It's in a quiet neighborhood and very secure. It's close to the Metro, just a few quick stops to Termini. In addition, it's a short walk to the regional train station for quick transport to FCO airport, Trastevere, Ostiense. There's a good grocery store a few blocks away. Plus Sergio was very responsive and provided helpful guidance for restaurants and area tourism. Highly recommend.
