I stayed here with my boyfriend 5 nights in May 2019. The host met us at the building when we arrived and showed us the way to the apartment. It felt like an authentic old Roman apartment. It was bright with a very nice view from the balcony of the dome of the Tempio Maggiore di Roma and the top of the Palazzia Venezia. We could see also a bit of the street of the Jewish quarter where we sometimes heard a Street musician playing Hava Nagila and other tunes on his accordion. The bed was very comfortable and the kitchen was small and efficient with plenty of dishes. The wifi was consistent. It was stronger in the living area than in the bedroom.
In the building, there about three flights of stairs in addition to the lift. The lift, which was custom made to fit within the old staircase, is tiny. No more than two people or one person with two carry-on suitcases can fit at one time. We always took the lift up at the end of our long days. We took the stairs all the way down, except when we were leaving with our luggage, when one of us took the lift down with our luggage. The stairs are quite uneven and it was necessary to hold on to the handrail at all times and step carefully. Other reviews mentioned loud birds. We heard and saw pigeons and gulls, including three baby gulls, on the nearby roofs. They mostly cooed during daylight hours and sometimes at night. The windows are quite good at blocking out some of the bird and street sounds, but they still can be heard. I did not have trouble sleeping with earplugs.
The location is great. It is near restaurants, bus stops, grocery stores and the Travestevere neighborhood. We like to walk and we walked almost everywhere: to the Colosseum, Vatican, Pantheon and Spanish Steps. Not all in one day, of course.
One thing, if you will be there the night when Yom H’atzmaut (Israel Independence Day) begins, expect outdoor festivities with an outdoor stage and loud live music playing in the evening that continues until around 11 pm.
