Cannot fault this hotel, it was a real oasis in Caserta, which is a busy, town. We came specifically to see the Royal Palace which was ten minutes walk away. The staff were friendly and helpful, the room was extremely clean and well maintained as were the public areas. The pool was set in a pretty, secluded garden and was a good size. Make sure that you have dinner in the Restaurant - it offers fantastic Italian food with a sophisticated twist.
The only improvement I can think of is to keep the pool open a little longer - it closes at 6.00.
