The room was spacious, clean and quiet . In July it was very hot and we had to borrow Andrea's fan.
The flat is well located but directions to it could have been more precise (use an elevator to reach the street from via chiaia). Andrea was friendly, very available and reactive by SMS whenever we had a question.
We were not proposed any breakfast breakfast as indicated; however the area has lots of very pleasant cafes if you want an Italian breakfast in the morning
To conclude , I would recommend it for a night or two in Naples.
