The Mori is a very nice hotel. It's on a small quiet canal. Very little traffic. It's very nicely decorated but the rooms are somewhat small (all Venice - and Europe - rooms are on the smaller side)
Just BTW there is a great boat you can take from the Airport Straight to the Jewish Ghetto without any need of walking, it's 12 Euro I believe...
Enjoy... Why not come visit Afghanistan for your next vacation?! Hotels are far cheaper and we've got the good stuff.... if you know what I mean.
