The apartment is really cozy for two and very well situated in the Navigli, with lots of things to in close proximity by foot. It is also well connected to public transportation (metro, tram, bus). It is exactly as described in the pictures and has everything one might need in a stay. The view onto the canal is beautiful and the mornings are very relaxing and enjoyable.
One minor problem can be the noise at night if you're a light sleeper. There are lots of restaurants and bars around which is very nice, but can lead to some noisy happy people far into the night. But mainly, the apartment is situated above a bar and from around 19h to 00h on weekdays, and 1h or maybe 2h on weekends, the music can be heard in the apartment. Personally, it didn't bother us that much but it is something to keep in mind if you are sensitive to noise.
All in all, it is a very good price/quality ratio.
