What a lovely place to stay :) the apartment is a great space, comfortable, everything you need in the kitchen if you're cooking in the evening, comfy bedrooms, clean throughout, lovely warm showers and a nice balcony. The location is great, if you like the tourist scene, it's ten minutes walk south of the apartment to St Marks square, of if you prefer a quieter scene, go north towards Ospedale for a less busy but equally beautiful experience. You have some great places close by, and are optimally located to take the Vaporetto around the whole of Venice.
If you're looking for a nice gift to take home, look for L'Arbero shop which is nearby for beautifully crafted Murano glass jewellery, you can meet the owner he produces his pieces in the back of the shop, and pick out something really nice to take home and know you've bought something from one of Venice's Artisans. Check out local bakeries for delicious breakfasts, there is a vegetable market stall three minutes away and there's a Supermarket just five minutes away too.
