Our stay at the Graffiti Art Pad was great. The apartment was very clean, location is amazing! Down the street from the British Museum, easy walk to many theaters, and to either Holburn, Covent Garden, or Tottenham Court underground stations. On the way back from either station there is a grocery store also, so picking up some breakfast supplies was simple. It was extremely helpful to have a (very small) washer/dryer (with detergent) available for a quick laundry run as well as a dishwasher.
The only negative that we found was that in the living room area, with the windows open it is quite loud from people on the street. The bedrooms are in the back and they were much quieter so it isn't a major problem.
