Minya is a great place from which to visit Beni Hassan, Amarna etc. But under no condition consider staying at the Nefertiti.
Individually the staff members are very charming but are totally incompetent when it comes to runnning a hotel. The facilities are run-down (sinks blocked, air-conditioning not working, grubby carpets ... the list goes on). The third floor of the hotel is a building site as is the area at the side of the hotel. There are simply no redeeming features.
The Horus Resort (which is directly across the road) looks to be a much better deal.
