The cave could be quite humid during the summer time. (However they instore air-con, so it wasn't too bad). Also, the hotel is located top of the hill, the slop is steep, could be quite a climb for people who have bad knees. Having said that, they offer drivers to transport you down/up if needed, and they are quite flexible.
Hotel staffs were nice, helpful and speaks good english. Room is spacious, and every room has a terrace/sitting area outdoor. The breakfast was very generous, it's impossible to finish what they offer! Gave us a good start of the day. The view is also amazing as well, every 5:30-6:30 we can see many hot balloons in the air.
