We needed somewhere to stay for my wife's Indonesian family - nine of us. The Sumaryo is the only place we could find in Prawirotaman that let us pack loads of people into two rooms. Personally I wouldn't have chosen this place had it been just the usual four of us travelling. Incredibly basic and not particularly nice. Cold showers and blocked toilets. Dirty/cloudy swimming pool. Old beds. As a previous review said - 'a complete dive' is quite accurate. On the plus side, it is cheap and conveniently located near many bars and restaurants, and only about 20,000rp in a taxi to Jalan Malioboro. The Indonesian side of the family were quite happy there.
