The pictures are factually accurate. Here's what matters (IMO). 1) the location is perfect!; 2) whilst the apartment is basic, it is authentic and spotless; 3) the mattress on the bed - they joined two beds together- was incredibly comfortable! I personally find these three points the most critical for a stay in Venice. (Trust me that you will be living the city not in your airbnb!)
The icing on the cake are the details: basic but very thoughtful breakfasts with yogurt and croissants, coffee, italian stove top coffee maker, milk and juice in the fridge.
Efficient, friendly checkin.
Super accurate instructions to get to the flat from Zuccaria pier (albeit you can shave 40min your journey if you disembark at Ospedale) and use your phone to get you to the apartment.
12 min walk to/from Ospedale pier where the vaporetto (water bus) can take you to/ from the airport
Safe recommendation and good value.
