How to get to Bird's Nest?

Hello! I just booked a hotel at Home Inn Huixindongqiao, it's at Xiaoying Road 11, Chaoyang District. I was told that this hotel is near the Bird's Nest. How can I possibly get to th National Stadium from my hotel? Which bus to take? and How much is the bus fare in Beijing? Also, what time do they close? We're planning to visit there this Friday

Thank you so much!
