There is a sign that says the window must be opened an inch to prevent the furnace from shutting itself off due to "safety". Sure would be great if they weren't relying on a sign to prevent unsafe conditions from being created. Just because a furnace has a safety shut off mechanism doesn't mean you should be actively relying on that. I asked the host about this several times asking for information which they said they would look into for 3 days before giving an actual answer which still wasn't exactly satisfying.
There was no hot water throughout the stay due to the water heater being broken. They kept saying they were sending someone to fix it, but it never happened. I'm only out there for 4 days to visit friends I haven't seen in 2 years. I didn't have time to help with some water heater issue, but it sure would have been great to have been able to take a shower.
