Street noise, but this is not the fault of the Domus, it is also typical. I rated everything as excellent, with the exception of comfort, but only because of my bed, it was a little hard, but this is a personal taste, not against the Domus, trust me, you will have a great stay here.
The peacefulness, the history, the beautiful view, the sisters, breakfast, etc. were all great. Had a very good stay. If in the Sorrento area agin, would defenetly stay here. It is a little hard to find, as I don't believe the street names match up, but if you go north on Della Rosa to T, turn left, go about a block to a blind curve on narrow street, on the right, grey gate #120, hope this helps my fellow travelers. Parking is 5 euros a day, and Internet is 5, sorry, did not use internet, so cannot comment. Showers are small, but typical.
