i really enjoyed every part of my stay at maria. To sum it up:
+ the location is GREAT. you are surrounded with culture in the middle of the city, yet you don't hear any noise from the streets in your bedroom.
+ the bedroom, the living room and bathroom were in exellent condition, just like the pictures. I really liked the fancy airconditioning.
+ maria's english was, in my experience with other italians, much better. she could answer most of my questions without any problem. she adviced me on good restaurants in the neighbourhood.
+ price/quality was really good. she should honestly ask more.
- the wifi was not very stable, sometimes it would not show up. if you are really reliable on that, keep that in mind (the cafe nearby had good wifi, that is where i went most of the time)
I really liked her dog, so for me, that was great. he can be really enthousiastic in greeting you at times, so keep that in mind if you dont like dogs.
