My prior job was in Wuxi, and my Mrs works in SH. I’d go to Wuxi by the D train every Sunday afternoon, and back to SH Friday evening.
Took about 2.5 hours each way. 30min driving, 1 hour by train, 15 min walk, 45 min subway.
I would seriously NOT do it on a daily basis… it wasn’t even something we considered to begin with.
Suzhou is not as far out as Wuxi thou, and depending on the subway ride and all, you will be able to make it back and forth quicker… But as the Walrus says, the daily travel will wear on you.. quick!
