I liked the studio of Irene. There are many advantages:
1 convenient location (to the station of Trastevere - 6-7 minutes walk).
2 you live in a caloritic area, which is preferred by calm locals (the difference of the troubled area of ​​Termini with a large number of emigrants and the tranquil Trastivere is like heaven and earth).
3 in the studio there is everything that can be needed for living (from kitchen utensils to the heater, which I really needed when wet through the rain under a downpour).
4 the design of the studio is tasteful.
Now about the minuses, but for me it was not a hindrance.
1 studio is located in the basement.
2 someone wrote in the reviews about the noise. But on my trip there was no noise. Sometimes it can be heard how the door to the entrance closes.
