We had a fine time at the Melusina apartment (12 days). The location is close to the famous Acqua alta bookstore and you reach Piazza San Marco within 15 minutes. A supermarket is nearby (Coop), they are equipped with almost everything you need (note: vegan food there, soy products such as milk or cream as well as gluten free products of all kind, which we appreciated). The apartment is really very basic, don't expect to much from the kitchen, but you will get along if you can live for a couple of days without a four course meal every night. There is no couch to relax on, so you have to cuddle up on the bed which is not a bad thing actually. Overall, it was a good choice for our extended trip to La Serenissma that helped us in saving some money that we rather spent in musems and galleries.
