I am sorry to say that my expectation was a bit high from the reality. We had to wait quite a while to be able to go to Dieng and planned to stay at Dafam hotel. The hotel location is in the city, walking distance to some convenience stores and easy to find local food. It is cold enough as per my expectation even in the daylight, with a beautiful surrounding completed with a small river panoramic view when we had breakfast. However, there are some improvements needed to maintain the pride of the hotel level (4 stars? considering the price level): 1. The receptionist (a man) was missing when we arrived for booking, so I had to wait even for a short time, until his co-worker finished assisting another customer. 2. The toilet is really smelly (room 517), it smelled like somebody had thrown their meal into the toilet and the hotel staff missed to remove it. I ordered 2 rooms, both of them were smelly. The other one, the bedroom was smelly. We didn't complain at the time as we could see the hotel was full, so we didn't think we would get another room, however, this makes us think twice to stay in this hotel again. 3. The window cannot be opened, however, there is about a 1-2 cm open gap from the window to its frame (it is an alloy frame window with a glass window, that used to be able to open it). 4. My family and I went for a morning walk after having dinner, it was so fun until we passed an area near the parking car area, which also smelled strongly of urinal. It could be a better experience.
