It was my 4th time in Rome and this is the place I loved the most. The location is great, you can check the Fontana Di Trevi from the window of the building (not from the room I stayed) and it is in the heart of the town. We are a couple that enjoy walking around the city so it was perfect for us (no need for paying public transport). 2.4kms away from Vatican City, walking distance from Piazza Spagna, Pantheon and Piazza Navona.
The place was clean, with nice details and an equipped kitchen.
The only two things to improve are: the shower, too small, but Italy is famous for its lack of space. And also the mattress, could be better. We would definitely come back!
