The Park Tower Knightsbridge, A Luxury Collection Hotel 

I decided to do a quick 5 day (3 full day) mother-daughter trip this January and stayed at the Park Tower Knightsbridge. I would recommend to others and would love to return again for a future trip! We were kindly upgraded to a higher floor and a park view in our booked category. Whenever we entered the room it smelled like mint, not like smoke at all as another review mentioned. Room service was the only thing available close to midnight upon arrival and it was actually delicious. Housekeeping was late in the day as another review mentioned (but we were out all day so it didn't matter) and one night we had turndown service which included closing the curtains, putting water at our bedside, and a chocolate, which was appreciated. You could hear street noise at night, but I'm sure that's due to the fact that we were facing the street and we aren't used to city noise in general. The location was my primary reason for booking at the Park Tower... the Knightsbridge Underground station just outside the door through the corridor off the lobby on the Piccadilly line (2 stops away from the West End where we spent 2 nights at shows), a few minutes walk to Harrods and a few minutes more to the Victoria and Albert Museum and their amazing Marie Antoinette exhibition. Every staff member we met was friendly and helpful. I recommend the Park Tower Knightsbridge, and hope to return in the near future!
