We stayed just for two nights at Alberto's place. It is a 10-minute walk from Venice Mestre, so not too far. There is also a bus stop close by in case you want to take a bus to Venice. The place itself is small but perfect for two people! I really like the way Alberto has kept/managed his apartment. The neighbourhood does seem a little creepy to walk around late in the night as some of the other reviews suggest but it is a stone's throw from the centre and honestly, manageable.
Alberto was also very quick with his responses and made sure our check-in was a breeze. Thank you, Alberto!
