One of the glass doors to the balcony had a white film on the inside of the glass that you couldn’t get to to clean, so we could only see out of half the balcony doors. One of the closet doors would come out of line every time we opened it and was just a pain in the butt to fix every time we closed it. The bed was very hard and uncomfortable.
