We stayed six nights to visit the Bienale. The apartment was just what we expected and more. The terrace has views over the roofs to San Marco one way and San Giovanni a Paolo almost within touching distance the other way. A few stairs to climb to get there, but this goes hand in hand with the experience. Giovanni lives in the apartment when he is home, and he has some personal belongings in the robes and cupboards, but there was adequate space for our things. Giovanni's son Pietro met us and got us settled in. He was helpful and explained everything that we needed. The apartment has an excellent new bathroom with a view of the towers of San Marco from a tiny window in the shower. The kitchen has everything we needed. The Ospedale area is a bit quieter than some other locations which suited us, and has a supermarket close by and restaurants just downstairs in the square. We were within walking distsance of San Marco and Rialto Bridge, and while at times we walked to and from the Bienale venues, the Ospedale stop on the vaparetto (ferry) is a short walk away and we used this to access venues as well.
We will defintely look to book here next time we are in Venice.
