What a nice stay! Shu was a very nice and considerate host. He prepared all kinds of snacks upon our arrival and was very responsive with messages. The location was very convenient and close to station (huge deal if you are using JR pass), and there was a really good food street very close to the house.
Our overall experience was very pleasant. I actually think this is a much better choice than a hotel room because it is more spacious! Shu lives upstairs (this is a 3 stories condominium) but we have never ran into him. You pretty much get the same privacy as if you had the whole condo to yourself.
