My wife, my 17-year-old son and I stayed for 9 nights at Chiara's wonderful apartment which is right around the corner from Campo San Bartolomeo. It is a short walk from the Rialto bridge and is at the heart of the city for easy access to just about any attraction.
Her place was clean, well furnished and most importantly the bedrooms were air conditioned for the hot Venice summer! The rooms were beautiful, clean and just as described. We had everything we needed for our long stay including detergent for the washer, extra sheets and towels, etc.
As described by others, one of the bedrooms opens up to a view of the canal which is on a gondola tour route. This is the room with 2 double beds and the other bedroom has a window that opens to a courtyard with a restaurant below. We made good use of the kitchen as my wife and I prepared our own meals from items we purchased that morning from the Rialto market (which is very close by including the famous Rialto Fish Market) and a short walk to the closest grocery store. This, along with several nearby takeaway pasta and pizza places saved us a lot of money on food during our stay. (The restaurant downstairs, Bacarando, also has a quick bite cicchetti (Venetian style tapas) bar that we also highly recommend! Delicious appetizers you can choose from the counter with a quick glass of wine or beer before taking off on an afternoon sightseeing!)
Chiara and her son Giovanni were very gracious hosts and very accommodating and checked in regularly to make sure if all was well and if we needed anything or any assistance. They provided us with some very good recommendations of local spots we may not have considered and Giovanni was nice enough to check us in late the night that we arrived because our flight to Venice was delayed by several hours. They even provided us with information on the best way to get to the Rialto Bridge boat stop from the airport that was both reasonable and efficient.
Overall my family enjoyed our stay and appreciated the centralness of the apartment's location to any place that we wanted to get to including Murano, Burano and Torcello. We highly recommend Chiara's apartment and couldn't have been happier with our decision.
