well just to update the thread as it was helpful to me.
the Sukhothai is very guest friendly, had up to 3 "guests" some nights and no questions or funny looks.
Suites are big and very comfortable.
3-5 min cab ride to patpong / silom rd. (depending on time of day). 3 min walk to local 7 11.
Only dowside is the expense, never ordered food in the 3 weeks I was staying due to ludicrous prices.
