The flat is in a basement, very modern, beautifully decorated in an industrial style. It’s a perfect location - in Roma, very close to historical centre and about 40 min by taxi to the airport in traffic (or 20 on a Saturday morning!)
The host is very thoughtful (for example, earplugs and umbrellas provided!) and responded to messages instantly - even though he was on a holiday himself. High standards in terms of cleanliness.
All the above made me feel as if, despite having only spent 3 nights in the flat, I’d lived in Roma for months!
