Kai is an excellent host, one of the best you can get in London. If you get to stay in one of his flat, you are the lucky one! Not only does he maintain his flat in an immaculate manner, he has an uncanny ability to know what his tenants need, even before you ask.
Blankets, Towels, Toilet papers, Pesticides, Bed sheet, Luggage carriage services, Lightbulbs, you name it! Kai will deliver instantaneously.
Not only this, from handy and practical tips that span London transportation, tourist places, food, places to go and places to avoid, banking system to complex business knowledge (i.e. Contracts, UK real estate system, London business practices), Kai openly shares his knowledge to you. The kind of service he provides are a mixture of chamber of commerce, tourist agency and a hotel. Listen to him and all will go well.
I would wholeheartedly recommend his place to anyone visiting London.
As I said, his flat is clean and spacious, and he really knows how to operate this business. For example,
You will never have unwashed dishes in Kai's place
You will never see people smoke, drink or take drugs in his flat.
You will never see people talking loud after certain time.
For those trying to settle in London, I would highly recommend him.
