We booked a flat for 5 weeks and he also was realy kind to take us from the trainstation in tsurukawa to the flat by car, so we didn't needto carry our luggage to the flat.
The flat itself was more than enough for 2 people and has well equipped kitchen ( gas stove with a oven and grill function, electric kettle, rice cooker etc. ) but you don't have to cook by yourself, you can easily walk about 2-5 min and reach many restaurants like curry, shushi, burger, ramen and so on, their's even a supermarket, a drug store and other stuff.
So about the trainstation, you only have to walk about 10-15 min. and can reach Tokio and the different districts quite easily.
If you have any problems you can rely on Ken, he gave us tips where you can find good spots for the sakura or some local spots for eating, buying souvenirs etc. also his english is very good so you won't have any problems to communicate with him.
So we can just highly recommend this flat for anyone who wants to go to japan.
Ken is definitely one of the best hosts on airbnb!
