Accommodation In Sakon Nakhon

i am living in phon ngam 30 km. from sakon nakhon. sometimes we go to sakon for shopping and we want to stay in the city center for 2 or 3 days in every week. i dont want to go and back from my home because the phu phan road have very sharp curves i dont like to drive and we dont have bus option they finish after 2 pm. we decided to rent apartment in the center. is there anyone who have information about apartments in sakon and the prices? this will be the second place for us so i am not thinking to give more than 4000 or 5000. thanks for your help
