I recently stopped over in Bangkok and stayed at Tarntawan Place. The hotel itself was well above my expectations, and all the staff members I encountered were very patient and helpful.
A few days later, I was further pleasantly surprised when I received an e-mail from the hotel's director thanking me for filling in the guest questionnaire before I left. I had noted two shortcomings--a bedspread that needed a wash and the taxi to the airport organized by hotel staff attempted to rip me off. The director indicated he had instructed housekeeping to rectify the bedspread issue and, after identifying the taxi driver in question, banned him from collecting any other guests from Tarntawan Place. He was also very apologetic for both, although the taxi driver's bad behavior was not his or his staff's fault.
It really is encouraging to see a business not only excel at customer service in the first instance but also be open and receptive to feedback, which it then takes seriously and actions. I thoroughly enjoyed my stay, and the director's e-mail was the 'icing on the cake', so I will certainly be back next time I am in Bangkok.
