We stayed at Salvos place for four nights and we had a really lovely time! :)
The room and apartement (which we shared with our host and one other guest) was just as we expected from the descrption.
The communication before and during our stay was really fast and easy. Our co-host Jennifer provided us with all needed information and with a lot of useful tips for grocery shopping and eating out, which we gladly used to avoid cliché tourist 'traps'.
We were picked up by their lovely Housekeeper in front of the apartment alley, which was very comfortable and easy to find for us. To her we also paid the city tax (3€/night/person) at arrival.
We also took the time to cook at the apartment, which was not a problem in the fully equipped kitchen with space in the fridge for ourselves. Also sharing the bathroom was not troublesome at all in the morning.
Of course the apartment isn't directly in the city center, but we actually enjoyed that a lot and we could still very easily reach St. Marks Square by foot or Vaporetto.
Hope this information is useful to future travellers, to whom we can recommend Salvos Airbnb 100%!!
Thanks for having us :)
