The Manhattan hotel used to be a guest friendly hotel but they are no longer. If you want to bring a guest to your hotel room if you reserve this hotel, you will need to pay a joiner fee of 500 baht.
Other sites have this hotel listed as guest friendly and they are mistaken. I got confirmation from the hotel directly very recently that they charge a 500 baht joiner fee.
Here is that confirmation:
Dear Valued customer, Greetings from Hotel Manhattan Sukhumvit Bangkok!! Our hotel has cost for a joiner charge 500.- Baht per person. For your security, please kindly present her/his ID.Card or Passport at the Reception Counter. Best Regards, Reservation Teams."
