Location, location, this was a very nice place to be - central London in a quiet neighborhood, near by to a great coop grocery store, and the place is spacious for a studio, with very nice, soft floors. The flat is equipped with a stove/oven, dishwasher, iron, hairdryer, and other stuff which is a nice differentiator from other AirBNB and hotels I've stayed in for similar prices. I didn't get a chance to interact with Sybille during my stay, but checking in / checking out was fairly straightforward.
