I am sad to have to write such a poor review, but the whole experience was the worst I have ever experienced, in my 7 years using AirBnB. We arrived late on a Thursday night, at 22:30 pm, and so agreed to pay the 20 Euros late check in fee.
We were also asked to pay 70 Euros cleaning fee, which we did as we were tired and the host's helper, Valentina, was very rude to us, and said we could not stay there if we did not pay in full right away, which was an unnecessary attitude.
The whole place was filthy, floors sticky and with stains and hair, beds with stains, mattresses with pee, blood and other bodily fluids ( without going into gory details) and masses and masses of dust everywhere. The place has clearly not been cleaned before our arrival.
I would highly recommend taking precaution before staying here, the location is good but there are much better places to stay in Venice, and this did not work out any cheaper than other places.
Sadly the only bad experience I've had in 7 years of AirBnB, luckily we did get a full refund, only after days of stress and arguing, not worth the headache.
