Accommodation in bkk

hello,

i am looking for an appartment which i can rent on monthly base, without any half year or so contract. because i will stay in bangkok only for 2 month.start mid august.

should be located in banglamphoo area.

what i need is A/C and maybe a little balcony. not necassary is something like cable-TV or furniture, exept a bed of course and a table.

and the cost should be really under 10.000 baht better something like 5000 baht.

and i would prefer a really appartmenthouse, then a longstay discount in a guesthouse with many backpackers.

thanks for your help.
