We had a large group of three related families (six adults, children almost 9, 6, 3, and 1), and this apartment accommodated all of us very well. The three bedrooms and two bathrooms were great for the three families. The air conditioning worked well. The washer and dryer were helpful. The location is great - near the train station and driving area - so that you don't have to carry or portage your luggage very far into the no-car zone. There are plenty of (boat) bus stops within a few minitues' walk, making it convenient to get around. There's even a very good gelato shop right across from the door to the building.
Silvia was very responsive, answering my questions about the apartment before we arrived. All in all, this was a wonderful experience!
