1)The host Kareen was late and we had to wait for half an hour outside since she didn't give a code for key locker and we were not able to enter the unit. I went to a parking where the key locker was paced, and to my great surprise, I found out that the locker was easily opened without even tapping a code. We felt very unsafe, as anyone could get the key and get into the unit. 2) Unit had a noticeable smell of bleach and other chemicals. We had to open all windows for a long time to clean the air inside and, so got cold. Host and housekeeper MUST make sure the air inside is not polluted with chemicals, but it is clear and fresh since they are hosting people who may have allergy. 3)Water stays in bathroom sink as it was clogged, and refrigerator made annoying noise that we felt uncomfortable during our stay, especially at nights. 4) On the first day the host Karen showed up late at 4:37 pm to meet us, moreover she was acting negligibly such as holding door with her leg.
