I had a great time staying at this Airbnb. My original housing fell through less than 48 hours before I was scheduled to arrive in London. Annej was very responsive and got everything settled on short notice.
The house is very easy to get to from Gatwick Airport. It is an easy train ride followed by a 8-10 minute walk. There is also a direct train that takes you straight into Victoria station. Croydon has a lot of places to eat, drink, and shop, so there is plenty to do for a night or two.
Annej was a great host. She is very friendly, gave me suggestions of things to do and helped me get all my travel plans sorted out.
