I stayed for 3 nights in Room 1 and it was perfect. The host was very nice and took care for every detail. The place is great located, very close to termini and all main attractions and you can walk everywhere. I totally recomended it!
The only problem could be that you have to go upstairs to reach the place and if you travel with heavy luggage could be a little difficult, but allways there is someone who can help you. The place worth it.
