Based on some research I did on the internet, including Trip Advisor, we decided to take a short side trip to Viterbo from Rome. Basically, I wouldn't recommend this to anyone, especially Americans. First, the train trip up there was the scariest experience I've ever had in all my world travels. We are almost mugged by a group of 5 teenagers who boarded the train at a stop by Viterbo. There was no one on the train to police their menancing behavior. Second, the Hotel Grand Salus is run down with poor quality beds. The air conditioning was off and we were told that they turn it off this time of year. The room was hot and muggy and overlooked the roof air conditioner. The staff was arrogant and unfriendly and unwilling to answer questions. The "spa" attendent was very rude and obviously didn't like Americans. The spa facilities were limited and the pool area was dirty. There is no reason for an American to venture into this depressed area and risk life and limb to soak in some thermal water, especially with the rude treatment by the staff and over-priced facilities. Stay away.
