Astrid is friendly, helpful and a lovely hostess. I stayed roughly 20 days in her apt. and I can certainly affirm that it was an incredible time with everything I needed for my stay, besides being a charming place with an accurate description.
The location was pretty good, close to the underground and around to some of the most important places in London. For me it was even more special because my school was 15 minutes walking from Astrid's place.
In general, it was amazing and I really recommend the place :)
