Ramune is a great host and takes care that you check in and out smoothly, making herself available to help for any sudden need. Communication was great, and she also made dome valuable suggestions for visiting. In addition she brought us great welcoming gifts such as coffee, chocolates, cake and amazing strawberries.
The apartment is generally well maintained and clean but there are a few points I need to remark:
1) the flat is listed as an entire place but in fact you will be renting a private room (with private bathroom) but will share the entrance and kitchen with travelers staying in 3 other similar rooms. This should be changed because some people will see it as misleading advertisement and might claim a refund. For me was still great as I managed to meet coop people in my solo trip;
2) the apartment is in a 6th floor and there is no elevator, which might be a constraint for some unfit or disabled people. This should be mentioned in the AirBnB page as well.
