One word: Excellent! Alex was super-friendly and even waited for us at the station to give the keys in person. The apartment is her own, and all-around nice. Kitchen and bathroom are functional, the WiFi is fast, and in general the interior is stylish and tasteful (and not to forget comfy). The apartment is on the ground floor in a quiet residential neighbourhood, and we never heard anything of the neighbours. Alex even left a handwritten (!) folder with useful instructions and tips for the surroundings. We found it to be a excellent base to explore London for a few days. Absolutely thumbs up - we would gladly book again.
