Elsa & Karol’s apartment was lovely. It’s not big but it has a surprising amount of storage space and room to move around as well as all amenities you’d need for a city trip. They even left a big bottle of water for us and a binder with all information. When we arrived, Karol was waiting for us and showed us around, check out was really easy as well. In summary, they are great hosts and we will definitely try to stay with them again next time we’re in Milan.
Note if you are 3 people staying there: the 3rd bed is a sofa bed in the same room as the big double-bed, so don’t expect them to be in 2 separate rooms if that’s something that is relevant for you.
