Otti's place was right in the middle of everything, we could reach all major Sights easily and the Kitchen was clean.
The Fridge was spaceous and had an extra freezing compartment.
The Ceiling is a bit low(we 3 are 1,90m +) , but as should be expected by the pictures.
The place is very quiet, but just around two Corners the Nightlife can start.
All in all I would recommend staying with Otti to get a good impression of living in Venice.
