I stayed at the Luca's apartment in the beginning of August for one week. I have very good impression about the host and his apartment:
1). Location was very well in the near from Zara metro station and Milano Centrale.
2). The apartment was very well equipped with very good wifi.
3). The host was very friendly and gave me detailed instructions about his apartment and the city.
I did not meet any problems or drawbacks of this apartment and, therefore, I recommend the Luca's place for all people.
