This place has a great location. My sister and myself walked and looked at just about every major historical landmark (Big Ben, Buckingham Palace, London Eye) Pimlico underground is close and is you do not follow googles walking directions you will get there even faster. It can be hard to find, we walked in circles for awhile, but eventually found it.
They were very accommodating with letting us leave our bags at the apartment early. As well as converter plugs, slippers, and towels.
Great place to stay if you want to be close to central London attractions.
