We stayed with my friend at Takeshi's home for 3 weeks and it was very nice experience. Takeshi knows english (his wife doesn't) and there was no problem with communication. House has two rooms so they may be other guests. That's not a problem for us. Home is clean and surrounding area is quiet. Every room has air conditioner. Our room was very comfy. For longer stay it's just fine for two people. You will get clean towels, fresh bread for breakfast, fruits, coffee. Quick tip: Chitose - Karasuyama St. is better choice than Roka Koen if you want to easily go to other parts of city. You can catch an express there and there are more shops and restaurants in area.
It's a good place to stay. Takeshi and his wife are really nice and friendly 😊
