I rented the apartment for work purposes for 4 weeks and it was quite perfect for my colleague and I. The apartment is great for 2 adults in separate rooms or 2 adults and 1-2 small children. The location is amazing, literally a 10 minute walk from the cathedral and a stones throw away from everything Milan. The apartment itself is very cosy and decorated nicely with interesting art and books, as well as the mini grand piano. The bedrooms are a decent size and the kitchen and lounge areas have everything you need. The apartment is an attic so in the heart of summer you will need the air-con on. Locals in and around the building are friendly and I'd highly recommend staying here. Although I didn't manage to personally meet Andreas, he was more than accommodating and helpful with everything and was available via phone to answer any questions.
