Standard 4 stars hotel. Perfect location and helpful staff. Pillow and bed are not confortable

The hotel is ok, the view outside the hotel is very beautiful. It is in the park, need to take a bus from the train station then walk about 5 mins. But there is no air-conditioning, as we go there in a hot weather, need to ask for a fan! The door's lock is hard to use, we need to ask the staff to show us how to use it. And as we had hang a "Do not disturb", the staff still lock our door for few times after 6PM!!
