My family enjoyed the stay very much. You should book now before Japan opens up to the world and it gets more expensive.
Best part is location literally feet from the station, restaurants, cafes (Starbucks) and the the like.
Pocket WiFi came in handy as well. Kids loved having high speed internet on their phones.
Yume is a great host and good with communication. Good English to make your life easier.
We will come back again.
