This is a very good value for money place! We stayed for a week and it was a calming and residential neighborhood to return to in the evening, after a busy day of sightseeing.
The place is small and a little old, but I thought that only added to its charm. Everything was very clean! The cleaning staff that came everyday to tidy up was super nice and polite.
Instructions were good and we had zero problems checking in and out of the guest house.
The downsides were the noisy road and the thin walls between the private room and the hallway. The room was also very bright throughout the night, since it's an old school tatami room with only rice paper style blinds. The duvet/covers were also very heat retaining - maybe because of polyester bedding?
But all in all - this is a good place that I would recommend, since it is hard to beat the price. If you take your precautions while staying there (ear plugs, sleeping mask and air condition), you will have a very comfortable time, as we had!
