Room & Service Great, Breakfast Shocking
I stayed at The London for the Easter weekend. The reception staff were welcoming and efficient, the room was large, clean and well furnished. Housekeeping were just fantastic.
I would definitely recommend The London for overall service, location and facilities provided you don't order food at the hotel (except in the Gordon Ramsey restaurant). 
I ordered a coffee on room service which arrived weak lke warm at best.
The waiting staff at breakfast were dismissive, didn't make eye contact or offer a table until I flagged one down, the breakfast was unappetising and service was awful.
