The apartment is just as advertized on the website. If you are looking for a very central place with an amazing view of the canals, this is just that.
The city invites to explore for the entire day, so the lack of comfort (like a TV, couch, WiFi) isn't that big of a deal. It is very rustic, but still very charming. It's a great experience waking up next to the canal, hearing boats going by. A gondola service leaves right outside the door, and you might want to look into reserving the balcony table at the restaurant on the other side of the street (Gorgeous, but we've been told you need to book 2-3 months in advance!).
Overall, a very good experience.
