Easyjet from Kastrup to Gatwick. Hold luggage only, no check in. One hold luggage really means ONE, no camera or “man purse” on the side. I had booked the tickets with Ingo Johansson and that what it said on the boarding pass. It says Ingvar Johansson in the passport, not smart. It cost normally DKK 720 to change it but the assistant was very nice and changed free of charge, thanks a lot for that!
Took the regular train, Southern, from Gatwick to Victoria Station (when we finally found the right platform and train). Takes little longer than the Express but is half price. Buy a train ticket that include day pass on the tube. Approx £15/pers. Continued with the underground from Victoria to Oxford Circus and then it was only a few minutes walk to the flat at Dufours Place (had problems finding that too, tip: get a proper map from the start ;-).
Booked the flat via airbnb.com. It had two bedroom, two toilets, a large living room area incl. kitchen and a balcony. Prime location:
1 min. walk to Carnaby Street
2 min. walk to Oxford Street
5 min. walk to Piccadilly Circus, Leicester Square and China Town
10 min. walk to Trafalgar Square and The National Gallery
15 min. walk to Buckingham Palace
20 min. walk to Big Ben, the Houses of Parliament and the London Eye
