Need advice on hotel stay in Beijing

My flight lands in capital airport at 9.30pm on Saturday night...I plan to take a flight back to India on Monday evening at 6.15pm....so I have almost 2 days to spend in the city.
I need advice on where to stay for those 2 nights...please suggest a few good hotels in city centre from where I can undertake sightseeing trips the next day...budget is around 200-300 rmb, should be connected well by metro and it will be great if there is an Indian restaurant nearby.
Also is it safe to travel from airport to hotel at that time of night?
I'll be really grateful for help !!!
