Small room, but great price. VERY clean and updated. Staff is super friendly, breakfast is good - croissants, meats and cheeses, yogurt, coffee, juice, etc.
Great location - 5 minute walk to the Vatican - you can see St. Peter's Basilica if you're on the correct side.
Small hotel, only five rooms - more like a bed and breakfast, with your own bathroom in your room, etc.
If you're looking for typical Marriott-style hotel, this is not it. But great for laying your head at night!
