If you are looking for an affordable, well-located place for a short stay in Venice, Lin Da's place might be just the right fit. It is just a couple of minutes away from the Venice Mestre train station and 7-10 mins away from the bus that will take you straight to the Venice islands, with plenty of tabaccherie along the way to purchase your bus and ferry tickets/passes. (Don't forget you can also take a train from Mestre to the Santa Lucia station in Venice, which might be better since the buses tend to get crowded). I would stay here just for the location alone, since it is conveniently located if you are looking at the more affordable options near--but not in--Venice. The neighborhood itself is calm with several cafes, bars and restaurants, and I felt safe walking back to the apartment late in the evening. The apartment is up a couple flights of stairs on the first floor (or second floor, to us Americans), but there is an elevator in the building which will make it easier on you and your luggage.
The room my family and I stayed in was spacious for three people and somewhat comfortable. We visited during the hot summer months, so it got quite hot and stuffy in there; if it weren't for the electric fan Lin Da provided, it might've been unbearable. One thing you should be aware of before booking is that you might be sharing the apartment with other guests in the other rooms. However, this was not a problem for us since there were two bathrooms with two showers and at least one toilet. The bathrooms themselves were very "lived in," with a tad bit of clutter but otherwise comfortable and clean. The room, however, was super neat and tidy. Beware of the bugs if you decide to crack open a window, though!
Lin Da and a family member greeted us for check-in and although she mainly speaks Mandarin, communication was efficient and everything went pretty smoothly. Lin Da is a kind and welcoming host. She will try her best to make you feel comfortable and help you settle in for your time in Venice.
