Should put up a signboard at the entrance by the main road. I missed it couple of times because the building was hidden from view by a construction site. The man at the reception, at night when we arrived, seemed to try to ask me for payment by pointing at the room price. I couldn't understand Thai, so I was not sure, but he only let me have my key after I pointed at my printed booking confirmation (in English). I wonder if I would have gotten my key that night had I not printed my booking information (which, surprisingly, did not say clearly that I had paid). Other than that, it was a convenient location to the Metro (only 5 minute walk) and to a 24 store.
