Location location location. Those are the three reasons to stay at this apartment. You will be in the heart of the city, and walking distance to everything that you need to see.
Romy's friend met me at the water bus station, and took me to the apartment. She explained the key system and answered all my questions.
Remember that you will have to pay three euros per night per person in taxes. She expects this in cash before you check in.
The room is small but functional and well decorated. The bathroom is clean and everything works fine. There was good hot water and good water pressure. Soap was provided.
Please ask ahead of the Wi-Fi is working, because it was not working when I was there.
Romy has a good system of keys which allows you to leave your baggage locked inside the hallway if you want to tour on your last day.
I would happily stay here again if I come back to Venice.
