We had a very enjoyable month here, and it was great to stay somewhere with a country feel. Some have pointed out that it is a little pricey to travel in to Osaka, but Genta's place is still good value for money (also, on both sides of the road leading to the train station you can find discount ticket machines. The ticket to Namba (なんば) is currently 550, there are lower prices on offer for week days in non-peak hours and weekends (the yellow button).
A cleaner keeps the shared areas in good order. (Even though you have your own living area with TV and fridge, the kitchen and toilet are shared. The bathroom is outside, but it's actually a nice experience to go out for a Japanese bath!) The cleaner is excellent at making sure you have everything you need, always refilling toilet paper and detergent, changing tea towels and sponges. The kitchen is well-equipped and there is a very reasonable supermarket nearby called "サンディ", as well as a 100 yen Lawson. There are also lots of washing machines on premises you can use for free.
We had no problems at check in as we found Genta's instructions very thorough even though the place is out of the way. When we had a sudden power outage (due to plugging in an extension cable and tripping the fuse) Genta was extremely quick and helpful in his response (note: we communicated with Genta primarily in Japanese but the information in the house is all bilingual and in many cases has Korean and Chinese too).
The room is downstairs and can be noisy depending on who is staying above (especially as it backs onto the kitchen with a glass wall. We moved our bedding into the larger room which was a bit quieter). The chance to stay in tatami rooms overlooking a beautiful Japanese garden is not to be missed! There are many beautiful small shrines and a gorgeous beach within walking distance (we reviewed some of these on TripAdvisor - they seem under-appreciated), and great places to eat nearby (さん天 or Santen for tempura is a favourite!) A very relaxing place for those who want to experience a less touristy Japan.
