Pier's apartment was perfect for us. It's down a small street that you might miss if you weren't staying there, so it has a very "live like a local" feel. The apartment is small but perfect with everything you need. We felt very safe and were very comfortable.
I did not meet Pier but he arranged for someone to meet us at the vaporetto stop and walk us to the apartment which was very helpful and she was very welcoming. I recommend staying here during your visit to Venice!
