The train station at hatagaya is not very convenient for us as we need to carry our luggage to walk up the stairs. If you are light traveller is should be ok. House location wise is good as it is very near to the train station. Walking distance is about 5 to 6min. I would not suggest if traveller is arriving at night time to transport using train unless you are light traveller and not travelling with the elderly.
House is very clean and you can actually stay up to 6people with the amount you paid per night. Information is very cleared in term on how to use the heater, water heater, washing machine and etc as they have a book with all informtation to instruct how to use it.
