Hotaka is a really kind woman living right outside of the busy Tokyo center. She has been helpful throughout my entire stay. Her English communication skills are great. She and her family are great people, and I'm happy to have become friends with them.
The house itself is located a short distance from Seibuen station, making it easily accessible by train. Summer visitors beware, as the path to the front entrance may have some plants overgrowing, possibly housing insects who would be happy to take a bite of new visitors.
Once inside, you'll have a big bedroom, with a nice bed, a desk and airco at your disposal. Additionally there is a kitchen with all basic utensils and a japanese style shower/bath available.
Note that the super market and convenience store are a little bit further away than what you might expect from central Tokyo. Normally a 15 min walk is no big deal, but the uphill walk can be a torture in the Japanese summer heat. Restaurants also require a bit more walking, but the best ones are easy to reach if you take the train at Seibuen-Yuenchi station. Keep an eye out for opening hours, as some of them are only open during noon.
Additionally, keep in mind that Hotaka doesn't ask for a cleaning fee, so you have to clean up after yourself. Just wash your kitchen utensils after use, sort trash like Hotaka will explain to you, and reserve about 45 minutes to clean your room before your departure, and everyone will be happy at the end of the day.
Summary - This place is for you if:
* You want a host you can interact with.
* You're OK with being outside the Big City.
* You don't mind cleaning after yourself.
