My stay at Franco's apartment was great. (Early October, 2015) Franco emailed me with information on how to get to the meeting point days beforehand, and was very prompt in answering any questions I had.

We met up with Martino, as Franco mentioned in his emails. He was helpful - gave us the keys, showed us the apartment - just as the photos show and clean!, and even gave us a snack bag of Murano cookies which was extremely helpful as we were starving!

The MAIN thing that caused us problem was the shower. By the end of the 4th day, we still couldn't really figure out how to use it. (Yes, the pressure is low as mentioned in other posts, but it's tolerable. ) In order to get hot water, you have to pull on a cord inside the shower stall. Exactly when does the hot water comes? Sometimes an hour later, sometimes right away, we have no idea. So, be sure to ask Martino to demonstrate when you get there - it's hard to grab hold of him in the day time as he's working.

Otherwise, the apartment is great - centrally located. We walked everywhere.
Some things to note:
Check out time was flexible - but the cleaning lady comes at 10AM, so you have to be out of the apartment at the time, and then you can come back to pick up your luggage afterwards.

Apartment is on the top floor, so just a word of caution. Views are lovely though.

It does get stuffy on the mezzanine, and you can't stand up straight under it.

Laundry machine instructions are in Italian, so bring an app to translate.
