The flat was clean and beautifully furnished. The location is central and well to reach by public transport. The check in and check out was uncomplicated and we felt very welcome by Alessandro and his friend.
The only difficult thing for me was that I couldn't sleep very well, because the walls were very thin. So we heard the noise of other guests through two nights of our stay quite loud and the street traffic at night and day (when in the apartment) through the whole week.
However, Rome is a noisy city :-) and the price was absolutely appropriate for this beautiful "Vatican Space"! We also received fresh towels and linens from our hosts, although Alessandro and his friends didn't have to provide anything. So this was a very kind and welcoming gesture!
