I honestly have not a single bad comment to say about both Alex and this place.
The place looks awesome: it is kind of a little "gated villa" in Mestre. The rooms are clean, comfortable, spacious and look great. You have access to kitchen equipment, washing machine and air conditionner (a must for those hot italian nights)! The place is easy to reach from the airport or the Mestre train station with Bus 15. From this place, a small 5-8 minutes walk will bring you to Bus 4L station that will get you to the historical centre of Venezia in 20 minutes or so. I strongly suggest you stay in this place: it is very calm, has a lot of services and shops near (on Corso del Popolo) and is a lot cheaper than staying on the historical center.
Our host, Alex, is very kind, easy going and flexible: he arranged an early check in and a late check out for us. We couldn't ask for more. It just added a little "plus" to our already fantastic experience in Venezia, one of the most beautiful place I had the chance to visit... Ever! :)
