The flat is very conveniently located in Trastevere, on the same side of the river as Vatican City. It’s immediately surrounded by plenty of restaurants and bars (across the street you can get a croissant and cappuccino for €2). We were there on a weekend and in the evenings it got very rowdy in the neighbourhood, but once we were in the flat we couldn’t hear anything (convenient for both those who want great nightlife and those who want a quiet evening in).
The only complication we had was getting there from the bus with our suitcases - it’s a neighbourhood with cobblestone streets so rolling luggage can be a challenge! Nothing against the apartment though. All in all, we would recommend!
