We absolutely loved our stay at Marta's AirBnB! The apartment is even bigger than it looks in the listing photos, and it is full of charming decorations. There are two bedrooms (a built-in divider can be pulled out to close off the daybed room), two large bathrooms, two large closets, and plenty of shelving/storage space throughout the apartment. The showers are small, but the water gets very hot and the showerheads are detachable, so we had no issue.
I found the bed quite comfortable - it's firm, yet has a soft topping, so it would probably work well for anyone. The air conditioning worked great, and we heard no noise from neighbors. The street is usually quiet, but when it isn't, the window shutters are great for blocking out noise.
The location is perfect, too. Trastevere is wonderful for being in close proximity to Rome's best restaurants after a long day of sight-seeing, and most of the popular tourist sites are within walking distance. We're really glad we stayed here instead of one of the other neighborhoods we were looking at.
Thank you Marta for being a wonderful host and helpfully arranging our arriving and departing airport taxis!
