Nice clean hotel in London, slightly cheaper than the other DoubleTrees. Everything was fine, nice and clean, as expected. Nice breakfast, however hard to get coffee to my table as the waiter always forgot. I had constant problem with the key to my room, and had to update the key 4-5 times daily. Irritating. There is no gym in this hotel. Nearest tube station is 15 mns walk away. All in all, 6-7 out of 10.
