Apartment on the first floor (but there is a lift). Easily slept our family of four in two large bedrooms. Nice living room and kitchen where we did prepare a meal.
Sylvia left a lovely stocked fridge with eggs, spek and condiments.
Great location, central and you can walk to most attractions, Colosseum 10 minutes, Trevi and Pantheon 20 minutes and Vatican a 12 Euro cab fare. Plenty of public transport nearby, Metro 10 minutes and cabs were easily available in the street below and well priced.
Many restaurants nearby to choose from, Sylvia was very helpful with some suggestions. Safe, fairly quite area although some road noise, but not excessive considering you are staying in the city! A well recommended apartment and host.
