Our stay was very short (one night) but perfect. The apartment (C'Laguna) was much bigger than we expected. It was modern, clean and comfortable with plenty of space. The wifi was great.
We would love to have stayed longer. Our host, Valentia, was very nice and accommodating, providing lots of helpful tips on which areas to visit in Venice (and most importantly, where to get the best food and avoid the more touristy places) and how to make the best of our short time. She was also ultra helpful with providing info for getting to the apartment via the various modes of transport in the city.
I would highly recommend staying here.
