We spent 2 great days in Venice. The location of the apartment is great. It's a 10-15 minute walk to all main spots in the central islands.
Chiara deserves the title Superhost. She'll tell you where to go, where to eat, etc. If you need more info, just send her a text and she replies almost instantly.
The apartment is great for a family. Fully equipped. If you have never been to Venice, look out the window to the canal in the early morning: watch how transport is done over water and how many boats pass below.
