I would recommend that Airbnb in case you look for an accommodation close to the city center and especially Colosseum.
The bedroom was very convenient.
However if you plan to cook there you could be disappointed. Moreover humidity is very disturbing when you stay there during the summer...
Melania always promptly answered our questions but when we did our check-in another person welcomed us and was not willing to provide us with local advice.
We expected more from that Airbnb.
