The Airbnb location is fantastic. Travestere is a great place to be based as out of the city centre but easy enough to walk everywhere. We loved the San Cosimato square too with supermarkets nearby and Travestere is a great place to eat and drink in the evening.
We did not have hot water for the first two days of our stay which was very frustrating but the hostmaker staff did everything they could until it was fixed. Beware that the keys to this apartment are tricky to use and difficult to get in and out of the building (they did warn us when we arrived).
Although the apartment was much bigger than we expected, the kitchen area is small and so if you plan on making a lot of meals at the Airbnb take into consideration that the area is a little awkward.
Overall we really enjoyed our stay here and would recommend this apartment to other people travelling to Rome!
