This place is amazing place to stay. New, very clean and the host is super quick to respond. All electrical equipments are new and easy to use.
For those who travel with children/elderly - using train will be difficult to/from airport. I suggest using limo bus to Shinjuku express bus terminal where you can catch taxi easily to the place. It cost about 800yen.
There are two supermarket within walking distance. One smaller and the other offer extensive grocery choices with drug store(tax free offer).
Removing garbage and changing towel everyday is an extra.
Futon is a bit thin on the hard floor.
Shared laundry will be difficult as you have to wait in queue sometimes and as a courtesy, to wait and pick them up as soon as possible so other can use them too.
This place is recommended to stay. Have a great time everyone
