I have now stayed at the Manhattan three times over eight years and have never been disappointed. The rooms are large enough and have all the expected fixtures and fittings. The satellite channels are limited to five in English, but that is a minor quibble. I asked for a late checkout at 6pm, because my flight was not until 10.40pm. They charged me 900bht (about $27aud). I didn't mind, they could've charged me for a full night and I would've paid. Much better than spending eight hours at the airport.
The hotel is perfectly placed for the Sky train and the underground system, being five minutes walk from Asok which is next to Sukhumvit station on the underground.
I have stayed in several other hotels in Bangkok, but I keep coming back to the Manhattan because it ticks all the boxes.

Our first stop in our holiday to Bangkok and Vietnam. Walked into the hotel and we were blown away. You expect budget hotels to be somewhat exaggerated when you see the pictures online but this hotel lived up to all that and more. The rooms were huge, the food in the hotel restaurant was good if a little pricey, the staff were very friendly and the hotel is located in the a very central and convenient location. Be it food, shopping, cinema, "entertainment" its all there within walking distance. I would recommend this hotel as a great place to stay for anyone.

Good value hotel with a great pool, comfortable rooms and many restaurants along the street and nearby shopping mall area. This was my second trip to Thailand, and my staying at Manhattan, I think that I would come back again this year.
The people who complaint here should consider the price they paid, I mean you can't expect 5* Hilton for this price with no issue, BE REALISTIC and fair!
But for the money is great.
