I loved staying at Ann & Ko's. They are really friendly and helpfull.
The house is located in a great neighborhood, safe and on walking distance from my favorite districts.
The bed is extremely comfortable, as well as bath and shower. Everything you might need, they have.
I was extra lucky, because Ann had made too much food the day before, so I had an amazing, tastefull breakfast. Next time I'm in Tokyo I will definitely stay there again!
