Paolo and Alberto's apartment is lovely. Just as pictured -- spacious and light. They aren't kidding about the stairs, though, which are pretty steep at the end and would be hard to navigate with a lot of luggage.
The location was excellent. Not too crowded, but lovely restaurants nearby and an easy walk to both the train station and the bigger attractions. Check in was easy, and Paolo very kindly walked me through all parts of the apartment (including extra sheets and how to use the washing machine). Would definitely stay here again!
