I had a good time at the guest house. Yoshi is really nice and everything was very uncomplicated. The location is very good, if you need something quiet that is still close to the city. It's just a short walk to the station.
Room 203 is the largest rentable one and I was very satisfied with it on my long term stay.
Only the kitchen does not meet European standards, as in a lot of Japanese houses. So cooking big, complicated meals is not possible, but it's alright for basic needs.
All in all I'd come again. Also the wifi is super fast!
