Stayed here for a few months while I was in Milan for work reasons. It was a fantastic experience! There are plenty of positives to mention.
The location is simply phenomenal. Plenty of great restaurants, cafes and shops nearby. Not to mention that you are just a 10 minute walk away from the famous Navigli area. Park nearby is lovely. Plus you also have a tram and a buss stop just down the road from the front door.
The building itself is very nice as well. There is even a very helpful receptionist who can collect your post/amazon packages for you when you aren't home.
As for the apartment itself- its clean, nicely furnished and has an absolutely massive outdoor terrace. Usefulness of the terrace depends on the season though. During the winter months I found it too cold to meaningfully take advantage of it but as the weather got warmer I found myself using the terrace every day.
I also cannot forget to mention the person who manages the apartment- Marina. She is extremely helpful, very easy to reach, understanding, accommodating and overall just a great person to interact with.
The only downside I can think of is the somewhat steep price, but if this apartment fits your budget i highly recommend it!
