The apartment is beautiful, in a lovely old house in a great part of town on a small canal with singing gondoliers going past; its very quiet but with 5 minutes you are in a lively, buzzing area with great bars and shops. And you are 15 to 20 minutes from St Marcos and the Rialto. It only takes this long to walk there because of the crowds.
Its possibly the best equipped Air bnb we've stayed in, it even had a stick blender in the kitchen (we wanted to shop at Rialto Market and cook something). And it was so warm and cosy, Venice is cold in February.
I was a bit surprised by the 30 euro fee to collect the key, but, as our flight was delayed and we arrived about 6 hours later than planned, it was well worth it to be met at the dock by Jim at 11pm and taken straight there.
A very lovely place to stay and if we visit again we will definitely stay here.
