There are some clearly great things about this place:
1. Uncomplicated to get to from Narita airport.
2. Convenient access to subway.
3. Very clean
4. Extremely friendly and helpful hosts. It felt lile staying with friends! They both have excellent spoken English and went out of their way to help even though my wife and I were extremely disorganized with our trip planning.
Other nice things:
1. Simple but decent free breakfast
2. Pleasant rooftop patio. The private double room also has a semi-private little patio on it.
3. Great washroom/shower facilities
Really, compared to what I found online in this price range, I think this is a great place for anyone to stay. Book it now!
