This place is in an incredible location BUT it's extremely loud. People were essentially screaming on the street below us until 2am, and then around 6-7am, a recycling truck came by and made super loud noises that sounded like it was crushing glass. We didn't sleep either of the nights we were there.
While it's listed on the 4th floor, in Europe they count zero as a floor, so you should know it's a 5th story walk up with no elevator except to send your bags. The elevator is also super sketchy and breaks. In the middle of the night somebody's bags got stuck on the elevator and they were sending it up and down and it was extremely loud.
I stayed here one night with my husband, and one night alone because he had to fly out early for work. I did not feel safe staying here alone as a woman. Creepy guys were loitering outside the building and when I came home late after dinner with friends I felt unsafe and walked into a store across the street to find my keys and make a plan to enter as fast as possible. You have to walk up a dark narrow staircase when you enter and it's a little spooky, and there's a big sign on the inside of the front door that says DO NOT LOCK so I never felt certain if the door was locked or not. Also, the door to the apartment is a bit jenky.
Lastly, I asked Giuseppe if I could keep my bag there for an hour after my check out at 11am while the cleaning crew was there, and he denied the request which I thought was a little ridiculous as it was only an hour and a bag in the hallway or on a couch wouldn't get in the way of cleaners. Not a big deal, I lugged my backpack to breakfast, but wasn't as accommodating as the rest of my Airbnb hosts in Rome.
All this being said, for the price and getting to stay in the heart of Travestere, it's a fun place if you're young and plan to stay up partying!
