The Ermanno the apartment is small but has everything you need to visit Venezia, is clean and the view from the window is amazing! You do not have to climb stairs with your luggage, because the apartment is on the ground floor and is very well located: it is close to the main streets and vaporetto stations.
Ermanno is very kind and did everything to behold our stay enjoyable. He explained in detail how to get to his apartment and found us at the Ponte delle Guglie to take us to the apartment (otherwise we would lose on the way). He also explained how the house works, offered a city guide, a bottle of prosecco and left everything at our disposal. In the following days, he sent messages asking us if everything was alright and if we needed anything.
The only thing that I missed was a wifi signal, and our 3G also had no signal inside the apartment, but close to the apartment there are cafes and bars where you can use the wifi.
Overall, my experience was amazing and I highly recommend the apartment!
