Kotaro and Kei are incredibly nice people. We had a really good time with them at their place. They made us visited Tokyo, they showed us the best view of the town and we went for dinner with them in really good restaurant. They are always giving you good tips and doing their best in order you feel good at their place. Their house is really well located, close from the subway station and from the line going all around Tokyo, which is really convenient to visit the city. The room is really clean and have everything you need. Kotaro and Kei also lend us a device in order to have wireless access everywhere in town, so we can get in touch with them easily. We deeply advise to anyone to stay at their place.
