The place is very nicely furnished and designed, and equiped in modern ways.
However, the place lacks basic sound-proofety, which turns out to be a very real issue in the specific area where the house is located. Also, the curtains are very thin (and even missing), making it very hard to get a good sleep in darkness (some people need that and artificial light can have a very negative effect on your sleep, which is kind of very important for life quality). Also, curtains are missing in the living room, making it hard to get a feeling of privacy and street dwellers and neighbours seem to have a direct view into your home. Hard after a day of work to set back :D Worked around the problem by setting up some linens on the windows, but I think this is just such a basic lack and shows some sort of missing coordination on the host side.
The place is 1st floor above a very loud gentrified area (bars, pub crawls crowds, partys, drug dealing, various hustling, shouting etc) and people aren't really caring much around here. You should know this first of all before you decide to book it. If you are in London to party for a weekend, why not. If it's for a business trip, or just spending an easy quiet time, I wouldn't recommend.
The communication wasn't ideal. Seems Luke isn't directly talking to you but some support team, and their communication was uncoordinated and incoherent. It was impossible to extend the stay by one more day, and the conversation lost its context as several people seemed to take care of responding.
