The listing says Eric works from home in the basement workshop. We took that to mean he would be working there during the day. It was not clear that he would be there around the clock. Had we realized this, we would have booked elsewhere.
When Eric came by the first morning, the person on the porch looked nothing like the profile pic that accompanies the listing. That being the case, we were alarmed and refused to open the door. When my friend asked, "can I help you?" all we got was, "open the door." If he had said, "hi, I'm the owner, Eric, just stopping by to say hi and check that everything is okay," or something remotely close to that, we would not have had a second thought about opening the door. I don't know anyone who would open a door to someone they've never seen before.
I sent an urgent message (to co-host Adam because he was the only one corresponding up to that point) that someone was trying to get into the house and we were afraid. Rather than try to put us at ease, Eric chose to chastise us for not opening the door. Eric called us impolite and stated that he could simply walk into the house through any door at any time, something I know my friends and I would not have appreciated and my guess is not many guests would.
The house was fine, the location was perfect. The only issue (and it was a big one) was the interaction with Eric.
