We have really enjoyed staying at this apartment. It is located in a grand 19th century building, has fantastic high ceilings and spacious rooms. Both showers, all kitchen appliances, TV and WiFi worked well. The weather was unseasonably cold so we had the heating on and it was more than adequate.
Roberta and the other hosts were very helpful, responded quickly to all queries, and made us feel welcome.
The location was perfect for our plans. It is only 10 minutes' walk from the Termini train station, but the area around the flat is not at all scruffy. Just around the corner is the delightful Piazza San Martino and a park full of archaeological treasures, which takes you to the Colosseum (while under your feet are the remains of Emperor Nero's vast estate, Domus Aurea). Ancient churhes with amazing mosaics, such as Santa Maria Maggiore and Santa Prassede, are literally on your doorstep.
The neighbourhood is full of pleasant markets, restaurants and bars (we loved Morgana recommended by our hosts and Astemio that we discovered ourselves). A decent supermarket, Conad, is in via Buonarroti, also within an easy walking distance.
More than happy to recommend the flat and the hosts!
