The appartment is very nice, located very central but still calm and only 5-7 minutes walking distance from the train station Venezia Santa Lucia, where you can also take all Vaporetto lines from.
10 minutes by foot from the appartment there is a nice canal with great restaurants and bars - it is great to hang out there in the evening with many other young people.
Fabiano and his wife are friendly hosts and were very fast in answering and helping us.
Unfortunately, there was one problem in the appartment: all the dishes and equipment in the kitchen was dirty when we arrived. We had to wash all the things we needed ourselves before using them. In our opinion, this cannot happen for 125€/night. Also, the kitchen was not very well equipped. It is sufficient for making breakfast or an easy pasta dish for dinner, but if you really want to cook nicely, you probably will not be satisfied (only 2 pots, most of the pans are old and not usable, no bowl for making a salad etc.).
Furthermore, we had to buy sponges to clean the dishes and toilet paper ourselves, because there was not enough there.
Apart from that, we really enjoyed our stay and the appartment is a great starting point for a holiday in Venice.
