The flat is very beautiful but shows many disadvantages. First of all, the flat is rented by a corporation. They will ask you more money if you arrive during the evening because they send someone to welcome you, even if you only need a code to enter the flat and not a key... in my opinion this wasn't usefull and this was a waste of money. The informations could have been sent by e-mails.
Secondly, the opening system of the building door is not efficient and has fragilitys. The second day of the trip, we stayed out during 30 minuts waiting in the cold before it worked again. According to the manager who came later in the evening to bring us a key, it happens a lot. So if it doesn't work well, I don't understand why they didn't give us a key in the first place. It's not very attentive and professional to take the risk that the clients stay out during winter.
Thirdly, the flat doesn't have a real heater. There is one in the bathroom, but in the living-room there is only an air conditionner and a little auxiliary heating. It's not sufficient, I think this flat should not be rented in winter for this reason...
Fourth, the boiler is very little, and the hot water lasts about 5-6minutes when your are under the shower.
Fifth, we had a power cut because we used the electric kettle and the hair dryer at the same time... the electrical installation is not sufficient either.
To conclude, I think there is a lot of things that should be improved, especially if the persons who rent the flat are supposed to be professional...
I'm sorry to say I was diasappointed and it broke my spirit during my weekend in Venise. I don't recommend this flat.
