Is this brian your butler or personal assistant by chance?
While it has been over a year since I stayed at Ballys, previously I usually had a couple nights there at the start of Thailand trips to get acclimatised and for the couple of nights in Silom and found it an ideal option. Right on the doorstep of all the places I expect to visit on a short break and rooms/facilities are perfectly acceptable.
Just to advise the Bt1600 for Studio is an all-year round rate, there is no difference between high-low season tariffs. The one-bed is also a reasonable priced option at BT2300 for Silom/Surawong as its very roomy and has the kitchen facilites as well (as does the Studio). Staff are excellent/very helpful, only odd thing about the place is that the main stairs only go down to 3rd floor, then from there to ground it leads only to a rear exit, so have to use the lift every time, prefer to use the stairs at all other times after the luggage has been taken to the room. Also excellent views around the area from the apartment on the high floors. Have booked a few nights here for next month at the end of my trip.
