Ciao! I stayed here for one night. I took the train to Milan Central and then walked to the Milan Rental location, which is a 7 minute walk from the station. Check in was very easy. They do allow holding of bags if you arrive early so you can still explore Milan beforehand without the weight of your luggage. The walk from the rental location to the apartment is 10-13 minutes.
The room was nice, very chic. It's a one floor walk up, there is a small elevator if needed. Very small TV, lots of English channels. The bathroom smell I see in older reviews is no longer there as of September 2019. The window system was a bit weird, it looked like glass doors that opened, and they did. However, the shade does lift up? At least I could not figure it out, I'm guessing for safety measures. There is a bottle of champagne upon entering the room which is a thoughtful touch.
