The place was great, just like in the photos (which are superb). It was very clean. The central heating system works perfectly, it was wonderful coming back to the apartment in the cold days of January. The apartment is fully equipped, Alessandro and Sara took care of every detail. They even gave us tons of good recommendations about places to visit and to go out.
The location of the apartment is awesome, just 3 minutes walking from Fontana di Trevi and 8 minutes walking from the Spanish Steps.
Bottom line: great place, good value for money, very welcoming hosts.
