Loved this place! It was truly a sunny and centrale apartment. The place is next to Santa Maria Formosa (a beautiful church and square). Go south from the square and in 10 minutes you reach San Marco, go east via Salizada San Lio and you reach Rialto Bridge in 5 minutes. Exit north and you reach Fondamente Nuove stop (from where you can visit the incredible Burano village - highly recommended)
We took Boat no 2 to San Zaccaria and were met by Alessandra's friend Mimi who directed us to the apartment. She was very warm, helpful and friendly. The place was spacious and clean. The kitchen was fully equipped and we had no problem cooking the 6 days we were here. There are two supermarkets (Coop) 2 minutes away. An ATM is in the Campo Formosa square. Wifi is available in the apartment even though it isn't mentioned on airbnb. Plenty of options to eat nearby and the neighborhood is not touristy. When going back, we took Boat number 2 from Rialto bridge to Ferrovia (Santa Lucia train station). Everything on our to-see list was very close from here.
