The location is perfect, near shops, convenience stores, the JR train Yamanote line (easy to use JR pass), restaurants, near the bus to the airport too. Super safe and easy to come and go. I have never met Lai but he answered every time I asked through the phone, very clearly. The room was newly decorated, very cool. The bed might be too small for two big persons, but it was OK for us and it has a good mattress. Dont expect a real kitchen. The bathroom was small and not very nice, but super clean. Convenient!
