Hotel Grifo has a great location - within walking distance of Forum / Colosseum and other major sites.
The front desk staff (Rosa, Alessandro) were very helpful every day with sightseeing tips, showing us on a map how to get there, etc.
Small breakfast area has enough to get you going in the morning - breads, milk, yogurt, juice, cheese, ham, turkey.
Nice terrace on the 4th floor.
The rooms are small and quaint, but good value compared to other hotels we considered.
