Apartment Wanted In Bangkok

Im looking to find an apartment for rent in Bangkok.

Im looking for something in a nice area, like Asoke or Phrom Phong.

The apartment must have cooking facilities, with an oven would be first choice.

It needs to be furnished and have gym, swimming pool etc in the building.. (a good gym with free weights and running machine)

Im preferably looking for a 2 bedroom, but would consider a 1 bedroom with a small office / maids room that can be turned into a computer room.

The apartment must have a phone line or internet access and be within 5 minutes walk to the BTS.

The budget is up to 30k per month, but would prefer 20 - 25 k range.

Standing by to look and sign contract.

Thanks.
