This apartment was very good in some aspects - the location in Dorsodoro and proximity to the Vaparetto (water taxi) was great! The apartment is a good size and nice kitchen and amenities. The communication throughout the booking process and during the stay was easy. The hosts were very communicative and even one of them met us at the water taxi stop to walk us to the apartment.
The issues we had were around mosquitos in the apartment. The windows were left open before we arrived and we found no less than 10 mosquitos in the bathroom the first day. We killed as many as possible, but there were more mosquitos every day. I left with at least 5 bites and so did my significant other. I recommend the hosts do not leave the windows open and I'm sure in winter, it is better.
Also, they have some issues with the door. Not easy to unlock/relock and it even broke one night which required us to leave the door cracked overnight. However, the host replied ASAP to our messages, came by that night and got the door repaired the next morning. Overall, a good apartment but does have some issues.
