The unit is spacious and located right in the middle, walkable to all the things you'd want to see. It's on the second floor of the building. The canal view is a plus, of course. There is well-written guidebook for guests to learn about the city. Marco recommended us a very good restaurant, perhaps one of the best in the city.
However, we couldn't say our stay was positive as we didn't have such a good feeling from the start. The interaction and communication with the host wasn't good and friendly. We were asked to meet in front of a restaurant, that appears to have no name in the front and could be easily missed. We couldn't find the restaurant as the GPS lead us to somewhere else. Nevertheless, we were no more than 5 minutes late. When we finally found Marco, he seemed irritated and told us that tourists often blame GPS when get lost. Then, we were rushed to the apartment.

Walking in to the apartment, we felt uncomfortable. It was dark and stuffy-smelling. Most of the windows were closed, not much sunlight in the unit like posted pictures, besides the kitchen and and the dining area and a little from the bathroom. The living room and master bedroom can really use some renovation. In fact, we ended up sleeping in the smaller bedroom. Other rooms are fine and renovated. Kitchen is well-equipped, which is great for long-stay guests.
Bottom line, we would not recommend.
