Very clean and well organised. The guest house is kept spotless and has all that you may need. From the rooms which are very well organised and each person has his unique space kind of like a small room to himself, to the temperature of the aircon, which too often is kept very low, whereas here it is kept cool but not freezing. The service is very good, there is always someone in reception from 7AM to 11PM and they are always ready to help. Toilets are super clean and well kept, and you are given 2 towels daily for you to use. Also, if you stay more than 5 nights, you get a new set of bedsheets to use (you have to change them on your own).
The kitchen is very well equipped and if you want to cook, they have all the necessary tools. Also, the common room is very well displayed, it is cosy and a nice space to socialize. An additional room to hang to dry wet clothes is outside of the back entry and can be very handy after a day at the seaside.
Overall, one of the best guesthouses I have been in during my trip in Japan.
