We have stayed at Palazzo Odoni before (but in the hotel, which is part of the same building). The palazzo is beautiful and in a perfect location. We liked our apartment, but there was a little confusion over the hotel and apartments being separate and it was not always easy to communicate with our host as (unlike the hotel hosts) he was not always around. It was possible to message him, but on our last day, we wanted to pay our city taxes and were unable to pay him in person. This was a small concern, and otherwise our stay was wonderful. The location is quiet, safe, convenient and very beautiful. I would recommend the palazzo (both hotel and residence) highly. One consideration though, is that there are a lot of steps followed by stairs at the entry, so guests need to be mobile.
