We stayed here just one night on our way to the rice terraces. Hotel is in an excellent location, very short walk to the bus and train stations making it an excellent choice for somebody traveling through. Room was nothing outstanding, but spacious and clean. Staff were very helpful and at least one girl spoke good English.
Downsides? Although practical, the location is on a very busy main road and not in the more attractive and quieter central area. The windows are also not double-glazed, so the traffic noise is constant. If you're actually spending some time in Guilin you might want to find somewhere quieter.
All-in-all, a good hotel with no major issues to report.
