The hotel is in a really good location, but the rooms are not perfect, old fashion rooms, they are not perfectly cleaned and not everything works. On my room the lights didn't work properly, tried to make a cup of tea, didn't work either.
The food on the restaurant is really expensive and the food is average nothing amazing, second night ordered service room and the food was bland with no taste and again expensive for what it was.
I wouldn't stay again based on the overall experience and price.

We've been staying at the Millennium for about 5 years on regular trips to London. Sadly, our most recent stay will likely be our last. The hotel has not kept up with maintenance or updates - the room we were in, despite being one of the "superior" ones, looked tired as did the public spaces of the hotel. I can say that the location is fabulous and given that the Millennium is fairly reasonably priced compared to some of its neighbors, it may still be worth it. But definitely not up to its former standards.

The location, facilities and the service of this hotel is excellent. I had first a room on the 3rd floor, which was so noisy from traffic I couldn't sleep, but when I complained about it they gave me a room on the 11th floor with a wonderful view. The staff is very helpful and attentive and the concierge service was excellent. Breakfast is good and the cafe bar was also very nice. The furnishing in the rooms could be more modern, but it was still ok.

I stayed at this hotel on Jan 24-27 and Feb 1-3 this year. The location is very near to Harrods and Knightsbridge train station. The room on my first stay was not as big as I thought but the service provided by the staff were excellent. There are two professional concierge in the hotel which has an excellent knowledge of the city, Emile and Andy. Amazing gentlemen that provides a heartfelt service. On my return after a week, the management has upgraded me to the next room category which was very much appreciated. The receptionists were very helpful, specially Nimita (not sure if the spelling is correct), she always provide a service with a smile. Over all stay was great. Thank you so much !
