We are looking for someone who can give us a tour of the less popular but interesting points of Venice (we have been there before). Any help would be appreciated,
Check out this website. We have friends who have taken these tours and raved about them.
Take a look at the website for context Venice. I have used them a number of times and they do a great job. They do group tours with no more than six participants, and they also arrange private tours. I have visited some really interesting corners of Venice with them.
