Stayed in Ca'Laguna for 3 nights, love how it's close to the port, but also close walking distance to attraction without the being to touristy. The host was very welcoming and met us as we got off the port, and took us to the apartment, they even showed us good local eatery and was very contactable by email or phone.
The apartment itself was very clean and well equipped, from the window we can look straight out on the canal, there was three of us, so one slept on the sofa bed which was very comfortable. In the morning even with the boats driving through it still wasn't loud and did not disturbed our sleep at all.
The host was lovely, and I would definitely recommend this place to everyone.
