Joel was super responsive per email about the place and the stay although he was not himself around in person. His friend Caroline handed over the keys so check-in was smooth with no problems. The flat itself is quite amazing - the roof terrace is simply stunning and the great views continue round all the outside walls that give you a great view over London from the 8th floor.
The whole place was tidy and clean and furnished with all modern amenities and matching the description on airBnB - I can highly recommend staying at Joels place.
