The apartment is perfect. The Fontana di Trevi is literally around the corner and there are supermarkets and a lot of restaurants to cater everything you need. Everything was as promised. They booked a taxi to pick us up at the airport and were waiting for us at the apartment with all the information and gave us great recommendations.
The apartment has everything you could possibly need. It is very clean and there is plenty of space. Too bad it was always raining and we couldn't enjoy the terrace, but it looked great, too. We'll definitely keep this apartment in mind if we ever go back to Rome.
