We (two friends) spent three nights in this really nice place in Trastevere. Location was easy to find, near public transport (trams and buses, and four tramstops from Trastevere trainstation ...where you can travel from /to Fiumincino airport very easily with local train, 8 €, app 25 min). Also few minutes by tram to historical area, Piazza Navona etc.
Area is lively, but not noisy and felt very safe. There is also a market place and some grocerys nearby. Trastevere offers a lot and you can spend hours just walking around and sense the lively feeling and food aromas in the air ...
Apartment is quite small, NOT cramped and really enough for a couple or few friends to stay. Doublebed was good and firm and a few pillows per person to use. Kitchen utensils, Wifi and wardrobe functioned well.
Toilet is big enough, but for bigger person it might be a problem to get IN to "shower cubicle". There was plenty of warm water and everything worked fine. Place was very clean allover.
The very best thing is THE TERRACE! There is a table, deckchairs and lot of beautiful flowers .. and you can see "half of Rome" .. we enjoyed many nice moments there, having breakfast, taking afternoon naps, having nightcaps and just admire the views. Take care of a basil we bought;)!

Giuliana is very friendly host and flexible with timetables! Grazie!
