Looking for apartment in close proximity to the MRT

I am seeking suggestions regarding low cost apartment rentals in Bangkok.  I would like to find a "Thai" apartment building (where falongs now also rent) in the area of 5000-7000 per month.  This price range should include a/c, hot water, bed, closet, table & two chairs and a balcony.  The apartment building should have a lift/elevator.  I'd love to have a Burger King, Foodland, Big C in close proximity.  I'm looking for clean apartment that is managed well.  They do exist but probably tough to find.

From long term experience, at 5000 baht per month the average Thai tenants are working class and don't party/make much noise.  However, now-a-days there is the Chinese issue.  The Chinese are moving in to these low cost apartments and they can get loud and in your way

I would love to be located near the MRT, maybe in the Lat Prao area.  

If you know of any apartment buildings near the BTS, I would also be interested.

I am open to all good suggestions.

Thanks for your input.
