On social media, the promotion was "clean and tidy" because the owner was Japanese, they said.
My experience: the toilet was moldy, the bathroom was dusty, the sheets were stained, the pillows were so hard... there was a sofa with a bed, and my husband slept there, but it turned out there were bed bugs. There were lots of cats roaming around, which was fine, but they defecated in front of the room, which was so annoying that they even came into the room. We stayed for two nights, and the room wasn't cleaned, there were no toiletries, only towels, which were small and never replaced. There were no amenities, and the hot water was quite warm... when I turned on the hairdryer, the electricity went out.
The price was really cheap, and the location was close to Borobudur Temple. If it was safe, it would be fine with conditions like that.
