Nice apartment in a fantastic location, nice view from the windows as pictured. The boat noise mentioned in some comments is definitely very noticeable (especially on Fr and Sa) largely due to the simple (but beautifully old fashioned) drafty windows, however, you may regard it as part of the Venice experience: when the Venice kids go cruising on Saturday night, they have a “boom boat” for that, not a boring car like elsewhere. And where else in the world would you be woken at three in the morning by the siren of a speeding ambulance boat? Thus, listen, enjoy and be happy the landlord does not charge you extra for that. ;o)
The only true negative of our stay were the persistent mosquitoes in the sleeping rooms (in October!). Windows and doors were closed all the time, but the insects seemed to appear out of nowhere. Spent half an hour every night hunting those beasts and killed three or four of them doing so but there were always more to give you hell. Judging from all the corpses on the walls, others guests had been bothered before.
The Wifi access point was brought in only after our insistence and password was provided with an extra delay. Result: first two days no wifi. Lack of professionalism or deliberate tactics to save on mobile data volume on the landlord’s side? A real no-go for foreign guests who don’t have free data roaming. :o(
Finally, I think it is a nuisance that the guests are being forced to deal themselves with the complexities of Venice’s waste and recycling system. Which means that you’ll have to show up with your bags at a boat at Campo Santa Fosca within a short time window in the morning. Unlike waste, they accept paper and plastic/cans only every other day. Thus, depending on which day you leave, you will have to join either of the latter with the waste. Not well thought through.
