Subject: Paris Hotel near CNIT La Défense?

Hi Ziners, I need to book a hotel near CNIT La Defence in Paris in Feb. With the Euro where it is, I would like it to be less than 150 Euro for 2 people with breakfast, if possible. Since this is a business trip, I would like to be within 10 minutes walking distance and have a bath and room large enough for 2 people. Any suggestions for me? I can often be late for early morning meetings, so a hotel minutes away via metro would not be ideal for me. Thanks so much. Georgia
