1. Need a room close to the US

Embassy for a week in early January

I need a room close to the US embassy for a week in early January. My parents are going to the US embassy for visa interview on January 7th. I am looking for a place for them to stay around this date. Hotels are too expensive for them since they have been retired long ago. They speak Chinese only. Rent can be made through Paypal in USD or cash in CNY, if the price is right.
