@Mark116 yeah it's even harder that I don't have a car, and just don't understand people who bring them into cities like this. I mean, I kind of get it. I just don't expect it to be free.
I could probably touch up my directions a bit, though I think they're mostly clear. My city thankfully has killer signage (every 15-20 feet, and very clear).
The only comparable experience I had is driving to Montreal, I street parked outside my AirBnB and the signs are all in French, and my (French speaking) host was more or less like "Yeah I don't know what it says," and I did get a ticket (for I don't even know, because French), though the host then paid.
So like, sure you should probably be able to tell your guest what the sign immediately outside your house says (only if they can't read it their self, and Montreal is going to be a very unique anomaly), but I feel like otherwise guests should be more responsible for spaces (or look for places with free parking).
Admittedly, I'm pretty sure AirBnB is limited in being able to search by amenity and it can get overwhelming fast.
