Astrid is a wonderful host: incredibly open and accommodating, especially given that I arrived a little earlier than anticipated due to an ahead-of-schedule flight. Her flat is perfectly situated in Fitzrovia, right in the heart of central London; virtually everything is walking distance. It's cozy and I never felt like I was in an area where I had to worry for my safety as a young woman traveling alone -- and this includes traveling alone at night. Her house rules are simple and easy to follow, and she was happy to walk through them all with me and answer any questions I had. More than that, Astrid was a delight in that she walked me around the neighbourhood in order to acquaint me with where I was living; though I had been to London before three years' previous, I had never been to Fitzrovia, so her tour of the area was a great help. Long story short: Astrid is a delight, her flat is perfectly lovely, and I am so grateful that she allowed me to stay there for the week. A wonderful experience.
