I just can align with the other ratings. The apartment is as shown in the pictures and Luigi is a very nice host that replys to questions very quickly and even offers wrapped croissants for breakfast. His mother waited for us at the check-in and she is very nice too!
Just a quick side-note that has nothing to do with Luigis appartment: If you are planning on going to Venice I would recommend to take some mosquitoe repellant with you :)
