The apartment of Sergio is very nice, cozy, clean, well equipped, has everything you need for a (short) stay in Milan. The building is neat and quiet and the location is absolutely great. You can reach almost all tourist-sites on foot. If not, the metro is few steps away.
We were welcomed by a friend of Sergio who gave us keys, some supplies to start with and some tips about dining in the neighbourhood. Very friendly and to the point.
We highly recommend this place.
