We were staying in Trastevere Loft during 3 days. It is located really perfectly - just 10-15 minutes on foot from Venezia square and 20 minutes from Vatican. The area itself (Trastevere) in our opinion is the best in Rome - cosy, romantic, with nice narrow streets, many bars and restaurants of different price level (many of them are recommended by Trip Adviser). Comparing with piazza Navona area (very touristic), for example, its really nice authentic place.
The loft itself was very cosy and clean. Many interesting things (models of ships, old furniture, books etc.) make the apartment unique, with its own "face". The most I liked that it is spacy (we had the table for 8 persons in dining zone and a separate zone with two sofas and small table). Free Wi-Fi was provided and worked really well. All facilities are electricity based and because of this are a bit limited in simultaneous use, however we didn't feel any discomfort with water or heating during our stay.
The host was so kind that allowed us to check-out several hours later. Thank you, Antonio and Alessandra for everyting!
