We had a very good stay at Katerynas Appartement! It's located in the heart of the city, perfect for exploring Milano. You need to know, that there is a bar downstairs in the same building, so there is a lot of noise until the early morning, so maybe not suiteable for light sleepers. Also, the sofa bed is quite noisy (the living room and the bedroom are connected to one room) and not very comfortable for an adult (maybe better for a child or a small adult).
