It's like staying at your friend's house. Yui and her family are very hospitable, helpful and polite. We were helped a lot by Yui's recommendations and various help she and her family gave us. We were treated very well by them and we were really thankful for all the help they gave us.
The place is very homey and we (group of 4) liked the place very much. It was clean, quiet, have all we need and are perfect for us who went to Shibuya a lot. I definitely recommend staying at this place.
