Mitsuo's house feels like an extended family in the cold and humid land of England. Upon arrival (11pm at night), I was warmly greeted by his daughter and him. His daughter even helped me to carry my heavy suitcase to the second floor. The room was big, clean and pleasantly decorated with a queen bed and a plush sofa. The bedding is more comfy than my own bed, and it smells fresh and clean. The house is in a very quiet neighbourhood so I got a very good night's of sleep despite jet lag. The toilet is also very clean.
Breakfast was extremely welcoming. There was a big bowl of fruit, all kinds of bakery, OJ, tea, coffee, yogurt...it felt like a treat. I chatted with Mitsuo's wife, and she said she really enjoys taking care of guests. You can see it from the warm hospitality that they give to everyone. When I departure, Mitsuo printed out direction for me, called for a cab and talked to the driver to make sure he knows where to go. His wife and daughter even brought my suitcase down again for me. The taxi driver thought they were my family! What a nice surprise!
I highly recommend the minicab he can order for you from Heathrow. It is 35-50 pounded depending on time, terminal etc. it is definitely worth it.
