Nice stay in a very good location in Mestre. Our host, Raoul, was very kind and punctual - We got accommodated immediately although we arrived a bit earlier than we had told him and the usual check-in hours. Both our room and the rest of the apartment(kitchen, 2 shared bathrooms) were comfortable, very clean and nicely decorated. The apartment is situated 2 min away from the bus station (you have 24/7 Venice connections and the way takes 15-20 min at most). As well as that, Raoul provided us with some cakes and juice in the kitchen for breakfast.
What we didn't like:
1. the temperature in the room was very hot and humid, and there was no air conditioning, there was a fan but not really enough
2. too few electrical outlets in the room
3. the main light switch was outside the room, on the corridor - took some time until we found it :D
Overall, a very decent stay, we would most likely come back to Raoul's place next time we are in Venice.
