My info. might be out of date as it was around 10 years ago I stayed there,but as there were no replies I thought it might help.
I stayed there with my ex-girlfriend(Not LB!),at that time it was more expensive than the rates you were quoted.It was over 3,000 baht per night.
The room was spacious, with a nice bed an furniture. At that time its Indian restaurant was one of the best in BKK.I Don't know about now.Short walk to the BTS.
BUT.......The one thing you should check before booking is if it is joiner free/friendly.At that time it wasn't joiner friendly.My ex was ok because she checked in with me.
For a definite answer, Send them an email and make sure you'll be ok taking LBs/GGs back......What's the point in staying there if you can't!!!!!
As I said before , my info (hopefully) is out of date.Hope this helps
