We booked an apartment with a small kitchen so we could make food. The kitchen came with ants which was annoying. When we asked the receptionist what they would do about it, he got room service to spray the ants, I know I heard the receptionist mocking me about complaining about the ants, that wasn't very nice. There are very few people who would pay for a room with a kitchen if they knew it came with ants.
There was also ants and mold in the bathroom.
The place also insists on spraying the elevator and corridor with automatic fragrance dispensers and the smell was pretty nasty, it made me wonder what smell they were trying to cover up.
The hotels.com app wouldn't let me add photos :(
