My experience started with the receptionist giving me a room that had not been cleaned up - I had to take all of my baggage with me downstairs in order to get another room. The receptionist was obviously very sorry about this, and was not her fault, but was very frustrating.
The room was nice and big, nothing to complain. Without the hick up mentioned above, it was a very good stay. However, air conditioning could be improved.
The hotel was very close to central London, which was a plus for me.
