Stayed here for 1 night in Oct 12. Booked a double room on the executive floor and was very happy with my room. Newly renovated with flat screen TV, separate bathroom and toilet. Good quality products/materials used for the room. Buffet breakfast was the best we had in China. It's a true international buffet (unlike other Chinese hotels which claim to have international buffet but they serve China-style hashbrown, sausages etc which taste weird).
Staff were very friendly and attentive. We wanted to go to grandma's kitchen and they gave us clear directions. It was raining on our way out and they reminded us to bring the umbrella in our room with us. We booked the Impression Westlake ticket through the concierge and paid the full price of RMB260 per person (we heard that we could get discounted tickets of RMB220 near the lake but we didn't have time to scout). When we collected our tickets from the ticket counter before the show, to our surprise we were given very good seats i.e. first 2 seats in the first row.
We took the airport bus to the airport. Please note that you should walk to the opposite side of the road to Zhongshan hotel, buy the airport bus ticket from Zhongshan hotel concierge and wait outside Zhongshan hotel. Merchant Marco hotel bellboy helped us cross the road but he gave us wrong info (to wait at the open car park next to Zhongshan hotel). We missed the first bus that came as we didn't have tickets. As this is a public bus with Zhongshan hotel being a middle stop, they wouldn't wait for you. You need to be ready with your ticket.
Overall pleasant stay and I will definitely stay here again if I go back to Hangzhou.
