The hosts were extremely nice and responsive. They speak English and quikly replied to all my questions. The neighbourhood is very safe at night and you have a supermarket and some bars and restaurants nearby. A metro station is very near to the place ( 6 min walk) but beware that the connection with the center (Colloseum, Flaminio) is kinda hard. You need to change trains and in the morning you can wait up to 20 mins for a train to come. A bit difficult if your plane leaves very early in the morning as it happened to us. Uber and Taxi could be an alternative, but be prepared to pay around 20-30 eur.
