I hate to do this... I really do. I know most of the reviews if not all of them here are positive and amazed... I guess it just did not happen for us.
First we were greeted by Gloria, who was very nice and helpful. Took us through the apartment, gave us a tour and told us about the trash and the basic stuff. She was great!
The Location is the best part of this place... location, location, location....
Its about a 5 minute walk from the St. Lucia station, which in a city like venice is very nice. No need for Vaporeto, which for a group of 8 would cost just as much as a water taxi. So that was a HUGE plus for us. Quiet street but walking distance to everything, we walked to St. Marco and it took us about 25 minutes.
The beds were very confortable, and the sofa beds were too.

but.....
The washing machine did not work, actually it started making a very loud banging noise that scared the living crap out of us.... We texted the number given to us about it and all we got was a "ok, we will come fix it" 12 hours later, the next day.... and nothing. No, follow up, and they never showed up.
The kitchen did not have anything. No Coffee, no salt, no sugar, nothing...
I've stayed at airbnb all over the place and this is the only place that there were no amenities in the kitchen.
The Bathroom. The shower head was not attached to the holder thing, so whenever we turned the shower on, it would go crazy and flop around. There was a major gap in between the shower box, so whenever we took a shower the bathroom would flood, and we had to clean it up. The other bathroom box was missing a door, so we didn't even bother to use it, so we wouldn't have to clean even more.
Don't get excited about the AC, you cant use it during the day or during the night, but even if you wanted to, it only works in the hallway so not like you are all going to lay sleeping bags in the hallway, no use of using it.
The icing on the cake was as we were packing our things and running around at 10:45 am, (check out is at 11) the cleaning lady comes in and opens the door, sees that we are there closes the door and says on the phone "oh check out is at 11".
So location, location, location....but next time I'll look for something else around the same area.
