Nice enough, but I liked so much more Murano.
It is a nice city but in general, there is not soooo much to see in proportion of the times you get lost. Is not very clean and the gondola men are not so friendly. If you would like to see a mini-Venice with BEAAAAUTIFUL little colored houses, go to Murano. I liked it so much more.
Insider Tip:If you are travelling alone, want to ride a gondola but cannot pay 80 euros for 30 minutes, look for a family with four or five members since the 80 euros is a fixed price for one up to 6 people, so ask them if you can ride with them paying just your part directly to them, it works :D! Is a win-win. I only payed 16 euros for my gondola ride :)
