Staying at Marii's was awesome.
The room is really pretty, with a lot of cool details. The view from the room's window is lovelly, the typical historical center street view.
The location is awesome, you stay in the heart of Rome, 2 min from the Castell Sant'Angell, 5 min from Vaticano, 10-15 from Fontana de Trevi and 20 min from the Coliseum.
Marii is a super host, she was really kind at the check-in, to explain all the rules and everything and then was always sending messages to check on us and sent us really great tips of places to eat and see.
Awesome experience!!
