Don't stay here until he gets the place finished and learns some manners. Venice is a beautiful and unique town and to have someone ruin it for you by the way you're treated and where you're staying isn't worth it. He should learn not to be curt to his customers, especially my daughters! I don't even talk to them like that! Also, if you're doing something shady, don't involve me in it! I'm a very honest person, if I pay for a hotel or a taxi there should be no "sneaking" required!
