First of all, the apartment is not new (as the ad suggests) and is not well looked after. There are traces of spilled liquids on the furniture and the bed and the bedding are disgusting and should be replaced immediately. The whole place is in desperate need of a deep and thorough cleaning.
That being said, the location of the place is perfect. Almost everything is in walking distance, there are grocery stores right downstairs, and you can see the St. Peters’ Basilica from the living room window.
Frankly, we did not contact the host about the cleanliness since, we wanted to enjoy the beautiful city of Rome instead of dealing with such issues.
