We were a group of three, staying for two nights in total. The apartment is right across the central station and very well connected to the rest of the city. Even though the apartment is basically only one room, the interior designer did a good job in separating the sleeping and the living area.
We had two points that were not great, and I want to mention them to future guests (even though they would not necessarily prevent me from booking again): 1) The sleeping couch is not really a sleeping couch. It's just a couch you can sleep on. 2) The smell of the apartment is not the best. I suspect that people smoked in here before, it's not super bad or anything, but it's far from "fresh".
All in all: Was good for what we needed: Ideal place to crash on a two day trip to Milano. Thanks for hosting us and all the best!
