PROS - The location is the best possible and the apartment is charming, equipped with everything needed. Although early check in was not allowed, we were enabled to store our luggage at a nearby office, 5 minutes from the apartment.
CONS - The elevator of the building broke down, and, being on the 6th floor, my husband with back problems had to drag our 25KG luggage down all the stairs in the middle of the night. When this was communicated to Milan Retreats, their answer was a shrug and "what can you do, it's an old building." No solution was suggested, no compensation was offered. We ended up having a horrible night which resulted in physical pain because of their unwillingness to help, which is very unfortunate.
