Stayed at the Grand Millenium in BKK from the 27.02.2008-01.03.2008.
This was my first time in BKK and after reading many reviews here on tripadvisor I decided to give the GM a try as it's one of the newest additions to the many 5 star hotels in Bangkok. I didn't regret my choice at all. Altough there is always a traffice jam in the Sukhumvit area the skytrain station Asoke was just a 5 min walk from our hotel and it's the best way to get around the city centre.

We checked into the hotel around lunch time and could get to our room immediately. As I spent almost 1 1/2 in the stuffy taxi from the airport I was glad to be able to go the room. Check-in staff was nice and efficient and you felt truly welcomed there. Everything is brand new and looks great from the inside and outside. We had our room on the 9th floor and the room is just great. It's quite large for a standard room, has very good beds, flatscreen tv (with many tv channels in 5 languages), a large desk, big bathroom and rainshower etc.
Everything worked and was spotless just as expected from a good hotel. Breakfast was included in our room rate and was served on the 2nd floor in the hotel restaurant. The selection was really huge and quite good. You had fresh fruits, thai food, western food, japanese food, dim sum, pancake stand, salad, cold meat, cheese etc etc. The quality was not bad however the fruits were not so ripe and therefore not always tasty which I find surprising considering that the fruits are all local. However that's one very small detail.
I tried out the spa which was splendid. Everything is nicely decorated, the privaterooms are well designed, the staff is friendly and one can choose from many different treatments including the traditional thai massage. I found the prices were quite cheap and it was really good value for money.
Also the hotel offers individual tours to many attractions in Bangkok. We booked 2 tours with them and everything went smoothly. We had a tour of the Golden Buddha, Emerald Buddha, the palace and also a tour of the floating market which is about 1 hour by car from Bangkok and leaves already at 07.30AM.
To sum it up:
-great value for money
- very good hotel
-very nice furnished
-good location
-great spa
-nice staff

A truly great hotel. Close to the Skytrain, fantastic rooms and views

We wanted to begin our two week trip to Thailand a good but not too expensive hotel. This was just the job. It's very new so has a really fresh feel and spacious. The room was a fantastic (went for their basic rooms) with a bed my wife is still raving about such was its size and comfort. The atrium in the middle of the hotel is very impressive but not so good if you suffer from vertigo as all the rooms are off the atrium.

The only down side (but it's the same with most hotels in Thailand) is that if you're looking to eat or drink in the hotel you might find it a bit of a budget buster - my wallet yelped when the bill came for three capuccinos! However, the hotel is in a great location with the sky train nearby and only a short taxi ride from lots of lovely places to eat.

A very nice hotel in a great location. It has not been open for very long which may explain why the price is so much cheaper than other hotels of the same class.

The room comes complete with everything you need, include S-Video/USB connections to allow you to use the flat screen TV as the display for your laptop.

Bathroom is behind glass walls in the middle of the room- pretty cool and very romantic. But you can draw down the shades if you want some privacy. The location is a block away from the SkyTrain and the Subway.

There are a variety of restaurants, which all seemed pretty good, the two I ate in were great. A spa is located on the 7th floor and until the end of March all the services are 50% off. There is a pool of course and even a putting green on the roof, though I never saw it.

A previous reviewer noted some problems in the finishing of the rooms and sure enough there were a few nobs that fell off on the doors. They need to go through each room and check everything over or in a few years it may look like its falling apart. But for now it rates an excellent for its great value for money in a good location. Treat yourself in Bangkok and stay here, you won't regret it.
