Marianne is an awesome host.
I founded her at the very hour standing in front of the house in waiting, she is quiet easy going and like to make conversation which helps a lot to make you feel comfortable during your stay, with the fact that she's very attentive and helpful, ready to fulfill any request, she briefed me about the surrounding and gave me some tips for more convenience.
The flat it self is really underated, for a very affordable price you'll be settled in a very huge room with full furniture, including individual fridge, water boiler, microwave and so on.
You'll be provided cards notifying about the house's rules, they come in several languages even in Japanese!
You as well get a map pinning the shops and restaurants, it really feels like a hotel but with a friendly touch.
