We stayed two nights in the 'Cielo' apartment. The apartment is located on the third floor in a quiet area of Sestiere Castello, but was certainly a comfortable walking distance to the major attractions and to amenities (e.g shops, pizza and gelato). Alessandro offered to send us a map after booking but unfortunately we wouldn't have been home to have received it - this would certainly have been useful as the numbering system used in Venice is different to what I am used to in Australia and Google maps doesn't give an accurate address. Nevertheless, Alessandro's brother located us in Venice and brought us to the apartment when we were lost. The space is big and set over two floors, comfortable for the two of us easily. There is aircon in the main living room and bedroom spaces, the wifi is strong throughout the house, the bathroom is big and the apartment overall was very clean. We were very happy with our stay and would certainly stay again.
