We stayed in a recently renovated room called 'Butterfly Terrace' - with windows and beatiful rooftop views on both sides - with a private bathroom and great shower stall in the room (various settings of shower nozzles and optional radio- tuned to lively Venetian music stations). Do bring mosqito repellent and/or net - Venice is surrounded by water - so there are mosquitoes. Carlo's place is close to (but not on) the Campo S. Margherita- very fun to hang out day or night - with lots of places to eat either in the plaza or in streets close by. Sometimes noisy at night - but nothing a good set of earplugs can't handle (we slept fine). We appreciated the kitchen with fridge space - there is a grocery store close by as well as fish and veg stalls in the campo. Communication and check-in was fine - we didn't meet Carlo, but he responded immediately by phone, answering our questions and addressing our various needs. Also, people working in the building were helpful and kind - on our first night, the renovator/caretaker helped us find a restaurant we really enjoyed. Great place to base oneself for a Venice visit.
