You should know for sure how many people will be staying inside the house because (god forbid any last minuite change of plans occur) the host doesn't really know how to deal with surprises and we were accused of being "dishonest" even after we apologized as we did not know this would happen and paid the extra charges. It was a frustrating experience.
As for the property, the heater wasn't very stable and is very old, however it was immediately fixed. The bathroom's sliding door was jammed several times during the stay. Other than that, what you see is what you get.
