Host was lovely, very welcoming and friendly. We stayed here for a week and enjoyed it. The apartment is the lower part of the hosts house fitted with a shower, bathroom and kitchen.
Only minor concerns were it doesn't have is a TV and the family have 2 small gorgeous children which run around and make a lot of noise. This noise is quite loud downstairs. Must have wooden floorboards or something.

But overall, kazoku was very nice and her apartment was as described. Would stay there again. Just be aware lots of travelling to get to and from her house to manhattan. Subway, ferry, bus, walk. Over an hour
