We had a lovely 3 days in Venice at Rossella's nest. The location is right next to a waterboat station and 15 minutes walk to St Marcos. Rossella also throughly explained the ins and outs of the place and even let us store our excess luggage in her warehouse while we're hiking in the Dolomites. The place is clean, has all the amenities you need( pots, plates, fridge, cooker) as well as some fruit, tea, some food and Prosecco as well. Rossella herself was an amazing host, very friendly and quick to reply to any of our questions. We highly recommend you stay here.
