this place is indeed a fantastic budget option for solo traveler like me with its 3kY per night. Clean, good Wi-Fi, good host, warm & friendly.
It is quite far (20 mins walking) from the Otaru Station.
But, it's not an issue. You can take bus no.9 from Otaru Station. The bus will announce the next bus stop in Japanese. When you hear it announcing "Shinsenbashi or Senshinbashi (something like that)" twice, ring the bell & bus will stop at bus stop that is in front of 7 Eleven.
You can either ask the people inside 7E or just use the public phone outside 7E to call Motoko.
Motoko is an exceptional host that you may need before you want to start your other trips in Hokkaido since she has very good English communication. Her 2 charming kids will never bore you out!
I love the fact that i can walk up the hill about 20 mins to Mt. Tenguyama.
I would definitely love to stay there again if I go to Otaru again.
