That's it for pros. This property is strange and uncomfortable to stay at. Every room has 2 signs in it telling you what not to do. It would be hilarious if they weren't serious. There are threats of fines if you move furniture and warnings about how the fire alarm will randomly go off is certain doors are left open. Yet for all these precautuons, it is very run down. Theres a big stain on the sofa. The cookware was filthy. There's no kitchen towel to help dry cookware when you wash it. There's mold in the shower. There's also a creepy floor access panel by the washer. Where does it go? I do not know. There's no dryer, however you wont be able to wash your clothes anyway. There's a room guide with English to explain how to use the various appliances. For the washer, it says to turn it on and set the course and go. But that doesnt work. The water to the washer had to be activated first. The previous person staying here didn't figure it out because there was still soap waiting in the washer. Overall, a huge disappointment. Just save your sanity and stay in a hotel.
