The price listed on the AirBnB was $144 then when I did the booking, she claimed that there was an error and that the price was really $175. We agreed to pay that and did pay it. Then just the day before check in she asked for more money. We refused and she backed down. She claimed the additional was for bedding, towels, etc. The posting does not mention anything about extra cost for these things.
The apartment itself was nice and was close to the grand canal. The neighborhood is a bit noisy at night but I suspect that is true throughout the town.
