If you travel during winter, avoid this ice cave. The heating system is an old model, which requires manually lit, the instruction says "Without proper operation, it could cause explosion." I completely felt unsafe doing it on my own due to there being too many steps and points to check. It is not stated in the listing description.
There is a big hole in the bedroom windows that keeps letting the cool air into the room. The hole is just covered by a simple card box paper. This isn't shown in the listing photo or stated in the description.
They even let me light the heat on my own. They didn't even send a handyman here to light the heat until I insisted on canceling the stay.
With the heat on, it was just 60-ish degrees regardless of how high I set the target temperature. The thermostat displays incorrectly of the current room temperature.
The room is clean, good location. Think twice before you make decision.
