So many good things to report and happily no negative ones.
The location is fantastic. It's very quiet at night but you step straight out onto the waterfront. It's also steps away from a location used in an Indiana Jones film, which my boyfriend was nerdily overjoyed about when I told him!
It's about 5 minutes walk to a very well-stocked supermarket, less than 10 minutes to the Peggy Guggenheim museum and about 15-20 minutes walk to St Mark's Square.
There are very good restaurants close by and it's a stone's throw from the Alilaguna and Vaporetto boat stops. They are right outside in fact.
Top boat tip: go out the apartment and turn right, turn right again and walk down towards the Grand Canal to the bridge. There you can pay 7.5 euros for a Vaporetto ticket (#2 line) that will take you all the way down the canal and then back round to the apartment. It takes well over an hour and is a fantastic way to see everything, I loved it so much, I went on it 3 times! It ends at St Marks' Square if you want to stay on and not get off at Zattere. This is a great way to see Venice without paying a fortune for a canal tour if you're trying to save money.
The apartment is clean, the shower is fantastic (and massive), the bed is really big and comfortable, the kitchen is small but has everything you need, and the wifi is wonderfully strong and stable. As someone who works online for a living, this was vital.
This was my first trip to Venice and when I come back I shall definitely be staying at this apartment again. I've stayed at a ton of AirBnB apartments but this experience was one of the best.
