Checkin:
For us it was not a good experience at all. At first the "checkin manager" answered very late (60 mins before we arrived in Venezia), so that we felt insecure if someone would meet us or not. We wrote him around 7 or 8 hours in advance before our arrival.
Also he spoke english very bad so it was hard to understand him and the conditions of the checkout. But the conditions were at least written on a paper in the apartment.
Apartment:
You can smell cigarette smoke in the whole apartment. As a non smoker it is very disgusting. This is really terrible and NOT okay! A smoker would maybe not notice the smell. Also the apartment is not clean enough. After we removed the covering of the sofa in the kitchen our hands felt dirty? The sofa covering has not been cleaned or changed for years. At least there was good bed linen.
The lock of the apartment door does not even work properly. This could be easily repaired.
The best thing about the apartment is its location. It is very close to the Rialto bridge and the Piazza di San Marco.
air conditioning:
Only the bedroom has air conditioning. This should be written clearly in the description. It was really hot in all other rooms in summer. So this is a big minus.
Tax:
I don´t understand why the tax (tassa soggiorno) is not included in the price in Airbnb? Nowadays it is pretty uncommon to charge it in cash? Also they charge 4,00 € per Person per night. This is only for 4-star Hotels, not for private apartments by law! For private apartments in of the highest category the tax in venice is 2,5€?
