We were 4 and we had a wonderful stay at Mariella's place. It is a lovely spacious appartment fully furnished with quality equipment.
She and her parents were very available, they kindly welcomed us and explained absolutely everything during check-in to ensure our stay would be excellent. They also shared useful information about visiting Venice and the Dolomites, picking the top restaurants ...
The appartment is only a 15 minutes bus ride away from Venice city centre, and the bus station is 50 meters away from the building which is very practical. There are buses approximately each 15 minutes and even till late into the night. You can also reach the Venezia Mestre train station in 10 minutes by walking.
Also we had to check-out early and the hosts were very understanding and available.
I highly recommend booking Mariella's place which is very adapted for families and groups of 4 to 7 people.
