Great neighbourhood, 'Trastevere' is very lively with plenty of restaurants and bars, it is both authentic and touristic. Ideal location to visit Rome, I walked the entire time and it never took me more than 30-45mn to reach points of interest. The building is further up, therefore preserved from all the agitation.
Although it is very simple, with a tiny bed and limited furnitures, the room is calm and peaceful. Shout out to the the private balcony, opening out on a lot of vegetation, very pleasant!
The kitchen and the bathroom are partially shared with the other tenants (4 rooms + the owner's). Just like in a flatshare, it is everyone's responsability for the place to remain clean... although it is not always easy with a high turnover.
I stayed one month in total and had a very nice time. I would definitely go there again if I was to come back to Rome. Thank you Gabriel, Federico and Paola! Definitely a place to recommend!
