Really lovely space on a quiet Venice street. The apartment is in a retrofitted garage. It's very clean and well-appointed with good Venice character. We raised the garage the get cool air and it was a delight. There's an amazing roof space which we didn't have time to take advantage of. The only minor qualm was that the shower door is a little awkward and needs to be opened with the shower off, otherwise water will get on the bathroom floor.
The space is behind the primary house. I'm not sure whether this is also a short-term rental or the hosts' residence, but we didn't see anybody inhabiting it throughout our several days there so it felt very private.
