This is a beautiful, 100 year old hotel. The rooms are spacious for a European hotel. The furniture seems as old as the hotel, although in excellent condition. I thought the chairs, etc., were comfortable but my wife did not.
The staff was very acommodating.
Free breakfast from 7-10am was very good.
The location is excellent but busy. It is located in the same square as the Italian Parliament, so there is a lot of police presence nearby. It is a short wall to the Pantheon and plenty of restaurants and shopping.
