I stayed for 3 nights and it was very pleasant. The facilities were good, although the water heater was difficult to adjust the heat, hehe. Unfortunately, my room (a family room with 4 beds) didn't have a refrigerator. I've checked into other rooms that had refrigerators. Hehe.
Hopefully, in the future, there will be refrigerators in every room, which would be even better.
For families planning a vacation in Yogyakarta, staying here is highly recommended.
