Perfect location, very clean, enough towels and soaps, cute interior. Beautiful main bedroom. They even put plenty of small coffee packets for automatic espresso machine. Check-in with self lockbox was flawless.
To improve:
Couch-opening bed in the living room is not comfortable at all and when moving you hear wire springs a lot.
No personalized touch at all, they manage many apartments, answering message can take several days and everything apart from the tour they sell is too much effort for them.
Basic things in the kitchen missing. E.g. no toaster and they don't have wine glasses at all. Not having wine glasses in Italy as a wine country and Venice is funny at least. I asked 5 days before checkin that it's my birthday if they'll put and they said they couldn't manage to find them. Hence I had to bring my own glasses.
Apt is on 1st floor, walls are super thin, so neighbours could wake you up.
They need to warn guests about mosquitos and ideally provide electronic two mosquito devices for bedroom and living room. If they told me I would have brought my mosquito device, we all got many bites and woke up during the night. Repellent can help, still not the best solution for the whole night.
For 140USD it's OK value for money for Venice apartment. Great for couple, for more people if they improve above things, especially sleeper sofa.
