Be wary - staying on this street you will get little sleep. We were awoken both nights around the hours of 1 and 2am by hordes of people literally screaming (without exaggeration) on the streets below. We were convinced that a riot had broken out the first night, until we realized it was just people partying. The lack of respect on the part of the people on the street was astounding - when I say screaming, I am not joking. People shouting at the top of their lungs every second. I am a young person (26) who has does more than their fair share of partying, but have never heard anything like this, and was shocked by the lack of consideration for the hundreds of people who live in the apartments above the party zone. You will simply not sleep here.
In the morning, if you leave the apartment before 11am or so, be prepared to walk out into literally trash heaps. The party-goers, and more importantly, the bar owners, have absolutely no interest in taking care of their garbage. They choose to leave it (ALL of it) on the street, scattered about, for the garbage men to come by and clean up the next day. Disgusting and disrespectful - not only to everyone who lives in Trastevere, but the city of rome itself. The streets looked like *actual* trash dumps RIGHT outside the door of the apartment. Just nauseating and wrong.
Finally, some little things. The key to one of the doors in the apartment is horribly finicky - be prepared to spend 1-5 minutes trying to lock your apartment every time you leave. The door to the space is also incredibly frail and would fall over with one kick from a child. Very safe and secure.
The apartment has very low ceilings and beams that hang down to roughly 5ft or lower in all rooms (main room, bedroom, bathroom). My girlfriend, who is not a clumsy person, banged her head half a dozen times in just two nights here. It was clearly an old attic space that was converted to be a living space, but is barely passable as one.
Lastly, if I’m being picky, the “king” looking bed is actually just two twin beds smooshed together (hah) and is pretty uncomfortable. Oh well.
All in all - I can’t wrap my head around how this apartment has so many good reviews. Avoid at all costs.
