Kristofer's place is located a few minutes away from all the main atractions in London, only a few steps away from train stations and even a rent-a-bike station is outside the building complex so there is easy access to everything, to pick up the key we had to walk 3-4 blocks from the house to a shop and they handed the key, it's was easy and convenient, it is just a self check-in . everything in the house was clearly marked and even when we didn't meet Kristofer in person he was always accessible via Airbnb chat.
