Me and my sister stayed 4 nights at Kazu's place. The room is quite spacious for both of us, and we were provided with complete amenities (washing machines and kitchenette are available).
There is no elevator available, so it's quite a bother especially when you're bringing heavy and big luggages.
Around 10 mins walk from nearest stations (we prefer walking to/from hasunuma station).
Jun is very quick to reply to our queries and helpful.
Overall our stay here is enjoyable.
