We had a long stay and the apartment had everything we needed for a long stay. The apartment itself had a modern design with all the extras you could want, including a full apartment stereo system, dishwasher, washing machine; the air conditioning kept us cool as temperatures exceeded 42°C.
Fabio was friendly and responsive; he even gave us some local tips for restaurants and shopping.
The apartment itself is close to many restaurants, the Termini for venturing further out, and several grocery stores. They even had a gym close by. There was also a bazaar where you could get fresh fruits and vegetables at an excellent price. The Colosseum was a 20 minute walk from the apartment
Overall, we would suggest this apartment to anyone looking for a comfortable stay in the heart of Rome.
