Things were very wrong from the beginning to the end. Bad stuff listed below;
The Check-in: Host Ra provided wrong address on listing. I reported that address to the custom when crossed the border (hope they don't catch me on the way back), we spent quite some time in the chat to get to the right building;
The service : no hot water, dirty sheet, paint is all over the place, broken bathroom;
The communication: no or delayed answers when ask help and none is resolved;
The description: no elevator and we have to carry luggage to climb 20 also stairs (what if there is elder or disabled?), no dining table/room, 3rd room can't be called as a bedroom;
The safety: strangers running/yelling/partying in the building common area through entire night till 6am in the morning, apt door shows a sign of broken in with force;
Of course, the big thing is my total payment of $435 USD per night, It made me the dumbest guy in the family vacation. Also, I only had 3 hours to sleep and you can imagine I was walking like a zombie with smelly hair (due to no hot water ) in Old Montreal.
Host Ra, thank you for ruining my vacation from the right beginning.
