We had an absolutely outstanding experience at Park Plaza London Waterloo. The staff went above and beyond for us in multiple instances, including bringing a bottle of wine and chocolates to our room when they found out we were in London to celebrate a birthday. Very modern hotel (fast elevators, touchscreen controlled lights, temperature, and curtains). Very walkable and great for transportation (next to an underground station, close to a train station, and only a five minute walk to the London Eye). Don't let the railroad tracks next to the hotel fool you, we never heard a single sound from them while inside the hotel. We would stay here again in a heartbeat!
