Here's a bit of a long review. Let's start with the good:
The location is great! You can walk to anywhere in the centre pretty quickly. The system to get the keys is great, the room is spacious and pretty, and although the toilet is small and separate from the room (you have to walk across the living room), it is fully functioning and enough for a quick shower in the morning/night.
Now, for the bad:
Walls sound isolation is non existent - you hear literally everyone passing by on the street at night, honking in the morning, people in nearby rooms, etc. - on our last night, there was heavy raining and thunders, and it felt like we were literally in the middle of the street due to how well we could hear it.. (of course not expecting the hosts to fix this since it’s an issue of the building)
The window blinds and curtains do not cover a lot of sunlight from coming in - personally, I need to sleep with silence and no light - which meant I couldn't get any sleep after 6am for 4 nights.
Wi-Fi signal was perfectly fine on the living room but it almost doesn't work from inside the room with the door closed - and of course this had to be the case since it's a shared home.
Also, do not forget that a tourist tax of 4€ per person per night was added - this is not specific to this place, though, but for the whole city.
Check out at 10am sounds too early for me (never in other places in Europe I have gotten such early times..)
Finally, a cleaning fee of 49€ is considered in the price, although we did not get any cleaning of the room/toilet during the stay or new towels ever - after questioning the hosts about this, it was explained that this fee is considered to clean the room for the next guests... which does not make much sense for me considering the price you already pay for the stay (almost 400€ for 4 nights)..
Note that the price paid in total (365€+32€ cleaning fee = 397€ total) was even more than what we had paid a few days earlier for a 4* hotel in Rome (which was better in every sense), so I thought you could expect a place to at least get a good night of sleep... but that was not the case in Venice - and both were booked with about 5 months in advance.
Overall, the place was OK but it didn't serve the main purpose that I booked it for - to get a few good nights of sleep - even though I paid almost 100€ a night. I reckon next time I will book another place with even more time in advance and bring some ear plugs and sleep masks just in case...
