My boyfriend and I rented Arianna's apartment for 9 nights, including New Year's Eve. I didn't have much experience with AirBnB, and wasn't sure how I would like it for 9 nights, but it was absolutely wonderful. The apartment is better than the pictures show. It is up two flights of stairs, and there is no lift, but we didn't have an issue with this. The apartment is much more modern than indicated: freshly painted, completely new kitchen and bathroom, very comfortable bed with good bedding and "American" pillows. There are some antique tables and side cupboards, but not cluttered or full of someone else's personal effects, etc. The kitchen has everything you could want, including a new dishwasher, fridge, oven, range AND a washing machine (she even had all the appliance manuals in English conveniently right there in the kitchen - needed this for the washing machine). This last item was great as it allowed me to pack lightly. The heater worked well, and while we didn't need the air conditioner, I did notice there is one in the living area and a second in the bedroom. We also like how the bedroom and bathroom area can completely shut off from the kitchen/living area. Made it nice while we both tried to adjust to the new time differences. I could see this also being great if people used the sofa-sleeper. This apartment is on a very quiet square, but you can be in St. Mark's Square in 5 minutes. We loved exploring the Castello neighborhood - great shops, restaurants, and more that we might have overlooked if not staying here. Big added bonus: There's a grocery store literally just behind the apartment where you can get everything.
Arianna was a great host, even arranging for someone to meet us at the vaporetto stop as I feared walking around lost looking for the place upon arrival. We didn't meet Arianna, but any questions I emailed or texted were immediately responded to. We could've stayed a month or more here, and been so happy. Highly recommend this apartment.
