Francesco and Nina offer a quaint, quiet, and convenient place in Venice. We spent 3 nights here, enjoyed amazing restaurants across multiple neighborhoods, and walked across most of the city from this location. Nina was a welcoming host and made checking in exceptionally easy.
My wife and I agreed the bed wasn't comfortable, but this is quite subjective. We prefer a firm foam mattress, for what it is worth. Also, don't open the bedroom window or the Venetian mosquitoes will have a party in your room.
