Tiny elevators and only one was working. I arrived...

Tiny elevators and only one was working. I arrived around 2:00 in the morning because of a train accident that delayed multiple trains heading into London, so when I arrived to check-in, the front door was locked. I followed the written instructions by the entrance and rang the bell and could clearly hear it. After no one came, I rang again...and again...and again. After about 10 minutes, someone finally came, opened the door and told me that I should have rung the bell which they then tested and of course it worked. When I finally got to my room and prepared to go to bed, there was a noise coming from above me (I was on the top floor) which I reported to the front desk in the morning since the noise was continuing. They promptly sent someone to my room but the noise ceased minutes before they arrived. The noise continued off and on for the following 3 nights, but the level was not quite as loud and since I was getting in late after the theatre and was therefore exhausted, I put in ear plugs and went to bed. When I checked out, the woman at the front desk had a serious cough and was obviously sick and should not have been at work. I mentioned the noise issue but she was not paying much attention because she was constantly coughing. My stay was paid for with a combination of awards points and cash. I have since made multiple calls to Hilton to get points for the cash portion but so far I have not been credited even though every one that I have spoken with at Hilton agrees that I should receive points for the cash portion of my stay. I checked out November 1 and continue to wait. I have stayed at this hotel before without problems and love the location. Based on my most recent stay, I probably will look elsewhere in the future
