The cave house is ideally located with stunning view. The check in/out process is simple and convenient. Elvira and Claudia were very helpful in providing restaurant recommendation and arranging transportation. The "minimalist" cave house is more than adequate and a fun stay for 5 of us.
One other note is, like all other hotels nearby it is 50+ steps from the street level. Perhaps Elvira can help arrange for a porter if you have heavy luggage.
