I stay the Ibis Suzhou SIP hotel. From Suzhou, I go to the Hangzhou by Long distance bus.

From SZ South Bus Station and North Bus Station, you can find buses to reach Hangzhou. The hotel has similar distance to reach either of the bus station, so you can reach either of the station to take the bus.
From your hotel, you can take the local subway line 1 to reach Leqiao Station and then change to take a taxi to either of the bus staion.
