We enjoyed our stay in Denis's apartment and would recommend to any couple travelling to Rome. The surrounding area of Trastevere is vibrant with plenty of cafes, bars and restaurants. You'll also be situated next to the Giancolo Hill which offers a beautiful view over the city.
The main attractions are within walking distance (North to the Vatican, East to the Colosseum) but Trastevere offers a break from the onslaught of tourists and allows you to integrate with locals in a safe area.
The apartment itself has a lovely balcony and is part of a secure residential block of flats.
