place to stay in Shanghai

Hi,
I will be staying in SH for one night before going to Pudong Airport for an appointment the next morning at 7.00 a.m. using subway line 2. Can you kindly suggest any average or budget hotel to stay, hopefully within walking distance along Subway line 2 at Stations : Century Park, Shanghai Science and Technology museum, Century Avenue or Longyang Road Station? Thank you very much for your kind reply.
