The location of the flat is really good, especially for those visiting the biennale. Both main venues are within walking distance.
We had some problem with the wifi on the first day and reported it to the host at once. The issue was resolved within a reasonable time (in the evening of the second day).
Generally, the amenities are good (equipped with AC) and clean, and the hosts are quick in responding the messages.
The only thing we are unsure about is the late check-in fee. Even though we are informed in advance and explained about the reason (the fee goes to the third party company that takes care of those who check in after 7.30 pm), we still think 50 euros are a bit too high for a twenty-minute check-in service (also the staff that helped us with the check-in didn't seem to know much about the flat and was unable to answer basic questions such as how to adjust the brightness of the lights in the living room).
