The location and apartment were both great. We never personally met Carlo, but he was understanding and let us keep our bags in the apartment until we left (check out was at 11am and our flight was at 8pm). The only issue was that there were a lot of house rules, which caught us off guard. He asks for a €20 tip for his representative to pick you up at the boat and go to the apartment, but since we found our own way there we didn't see a reason to tip. There is also a €1.50 "city tax" per person per night that was an additional charge. The apartment was big and there is enough space for at least 4 people, although he only gave 2 pillows. All in all the apartment was good except for some of the harsh house rules (i.e. Not putting the heat too high, and taking out the trash every day between 6am and 8am).
