We stayed at the Grand Millenium for four nights and although a new hotel everything works like clockwork and the staff cannot do enough for you. The Tapas bar is great and with happy hour until 8.30pm where you get two drinks for the price of one it is great value. It is right in the middle of things and easy to get around with the Railway only 200 metres away and taxis outside.

Great gym, cute pool and the Club floors have great breakfasts and evening drinks with free internet.

This hotel opened in November 2007 and there are some excellent opening offers available at present and for just over £50 per night it certainly can't be beaten.

The decor of the rooms is, as you would expect, the very last word in contemporary chic. When you enter there is an immediate wow factor you seldom experience.

The standard deluxe room is probably on the compact side for a 5 star hotel but it has everything you could want and was very well planned and fitted out. The glass walls make the bathroom feel part of the room but there are roller blinds if privacy is desired.

Everything has a quality feel: the bed, linen, pillows etc and the bathroom has high quality fittings. The lighting throughout is superb - only one thing could be improved and that would be dimmer switches on the bedside lights.

The is a wall mounted LCD TV which was rather quirky to control. The picture quality could have been better but it was ok and looked nice.

The air conditioning was too cold and it seemed that no matter what temperature you chose it reverted to 23.5 C (and it felt colder than that).

The hotel is located on Sukhumvit Soi 21 directly acroos from the MRT station, exit 1. This is a very busy road and it can sometimes take 5 minutes to cross. Altermatively the MRT and Skytrain can be accessed from the same side as the hotel by walking 150 metres towards Sukhumvit Rd and using an underpass.

The Conservatory on floor 15 was quite pleasant but the lobby, bar and lounge areas did not grab me as much as the rooms; very modern and perhaps a bit too glitzy for my liking. I much prefer the Sheraton Grande in this regard. Likewise the pool area at the Sheraton is pure genius, giving almost a resort feel to a city centre hotel. On the contrary the pool at the Grand Millennium was very small and almost like an after-thought and not a place I would want to spend any time.

I also stayed at the Lebua and the Pan Pacific on this trip and will submit separate reviews. The Lebua is fine if you need the extra space of a suite and kitchen facilities ... and the views. The Pan Pacific had a kind of understated elegance about it and the rooms whilst elegant had no wow factor, bordering on being rather bland. So in terms of the room itself, the Grand Millennium wins for me.

Given that the prices were equal my order of preference would be: 1. Sheraton Grande; 2. Grand Millennium; 3. Lebua at State Tower; 4. Shangri-La; 5. Pan Pacific; 6. Westin Grande; 7. J.W. Marriott.

I haven't stayed at the Peninsula or Oriental.

I stayed at the millenium as they were offering a good rate of around $130. In response to an earlier review the service has now been sorted out.nothing was too much trouble in fact the staff made my stay very memorable.room service was well priced and of high quality.I have stayed in many of the five star hotels in Bangkok including the pen and oriental as well as both Marriott properties.this property surpasses them all on all fronts including service.great value!

We had three nights and the Grand Millennium early December. Yes it was the hotels soft opening but it was excellent. You did hear the odd hammer or bang here and there but it never once effected our stay. The rooms are one of the best i have seen in the world. We have stayed and many 5 star properties but this one is the best we have seen. We had a club room and the staff in the club lounge could not do enough for you. The only complaint we had regarding this hotel was the tiny pool that is in total shade after 11am. We had had 2 weeks in the sun prior though, so it was not the worst thing, but still a dissapointment. Also the rates are really really cheap at the moment so if heading to Bangkok stay here for sure.
