I will start by saying our stay was at the end of the Indonesian School Holidays when Yogya is very busy, and this was one of the few available hotels.
That said, it compared poorly to other properties I've used in the past, and to make it wore was at a vrey higher price due to the season.
The lobby is large, and looks like it was quite nice when new- 20 years ago. The tooms are adequate, and good sized, and I will say kept clean.
Breakfast was ok, but nothing that made me want to eat other meals in house.
The location was good, and as mentioned in other posts you could reach the bigger malls or Malioboro Street with a fairly short cab ride. The street in front is the main road from the airport and therfore busy. The security guards were great about watching and offering to help any guests crossing to the convenience store on the other side.
Conclusion is Average and not a place I will probably use on my return if others are available.More
