We really enjoyed our stay at Monti! The location is great - close to metro station, Termini station and just a short walk to Colloseo. There are plenty of restaurants, shops and markets nearby. The apartment is clean and quite spacious. There are lots od kitchen supplies on the kitchen so you can easily make meals if you like.
I have to say that the hosts were very flexible and super responsive whenerver we had questions.
The only downside or rather our impression was that the apartment could use some refreshment, e.g. wall painting.
