I would definitely stay here again, and I think it offered good value for an apartment in central Venice with a balcony, which is a rare treat in Venice at an affordable price. I know some people have had issue with the mattress, but both myself and my mother found it perfectly comfortable. It was a short walk to the supermarket and to there was a cafe just round the corner for breakfast or lunch. And a stones throw to St Marks square, The Accademia and the vaparetto stop.
The shower is also fine, you just need to be patient with it to heat up which is normal for an old building. The furniture is typically venetian. The instructions to find the apartment were great, and it was easy to access.
