The address of the apartment is Via Bezzecca 1, Milan.
If you arrive from Milano Centrale Railway Station, I recommend taking tram line 9 from Piazza 4 Novembre, next to the station, and get off at Piazza 5 Giornate (about 20 minutes journey), then a 5-minute walk. By taxi, it costs about 20 euros and takes about 15 minutes.
If you arrive from Linate Airport, by taxi it costs about 20-25 euros and takes about 20 minutes. Otherwise i recommend taking the M4 metro line to Piazza Tricolore, then tram 9 to Piazza 5 Giornate (a total of about 20 minutes), then a 5-minute walk.
If you arrive from Malpensa Airport, by taxi is quite expensive: 110 euros. I recommend taking the bus (there are several companies operating on this route, leaving approximately every 20 minutes) to Milano Centrale Railway Station (about 50 minutes), then follow the instructions above from Milano Centrale.
If you arrive from Orio al Serio Airport, by taxi is quite expensive: 120 euros. I recommend taking the bus (there are several companies operating on this route, leaving approximately every 20/30 minutes) to Milano Centrale Railway Station (about 40 minutes), then follow the instructions above from Milano Centrale.
