I really enjoyed staying at the Apartment - it's centrally located near the train station and the main attractions and is very well equipped (the only thing I missed was air conditioning as it was very hot on those days and opening the windows was hardly possible due to the noise in this central location). Even though the flat is a bit older, it is in good condition, clean and cosy. Federico welcomed me very warmly and gave me some good recommendations for restaurants and cafes.
Overall, I can highly recommend this accommodation for a stay in Milan.
