We stayed two nights for a weekend in Yogyakarta. Our main purpose was to visit the temples around the city, and do some sightseeing in the city. The hotel is in very good condition, and the staff is very friendly and helpful. They offered to arrange tours for us, but we ended up doing this by ourselves. They also arranged pickup/transport to the airport (for a fee), which was very convenient. The room was comfortable, with a huge bed. Pillows were on the hard side, but that's just really a small detail. All electric outlets supported multiple plug types, which was very convenient. All hotels should adopt this!
We opted to stay here cause of the proximity to Malioboro market street. This was a bit of a disappointment, so if we would go back, we would stay closer to Jalan Prawirotaman, which had lots of restaurants.
