I stayed in Valerio's flat for four nights at the beginning of May.
The advantages:
+ Valerio is very nice, polite, helpful. I had no issues with communication, he would reply quickly to my questions. He gave me some tips and recommendations where to eat.
+ The flat is spacious and has basic equipment - good for a short stay for a couple of guests.
+ Comfortable bed.
+ Great location - quiet and peaceful. Shops, restaurants, bars, cafes, grocery shops all nearby. Bus stop round the corner, metro station (Policlinica) within walking distance. If you like walking, you can easily get to Fontana di Trevi, Coloseo, Piazza de Popolo.
The disadvantages:
- Flat is in the basement, so it lacks natural light during the day.
- It's cold and damp, despite 25 degrees outside. There are no radiators and the heating worked only in one room at a time (you couldn't turn both of them on).
- The sofa bed is not comfortable, very wobbly, the cover has stains.
- There was no kettle, even thought Valerio confirmed that there was. I am a tea drinker, so it was a fly in the ointment.
- Chairs are very uncomfortable. The were covered with some white fabric and were very filthy.
- Broken toilet seat.
If you are coming to Rome only for 2-4 nights, you will be out most of the time and you are not fussy, then I'm sure you will have a good time in Valerio's flat :)
