Carlo is an amazing host. We were there during the heat wave and Carlo ran out to get us a big fan for the apartment. He gave wonderful recommendations for restaurants and bus routes, etc. The location is perfect for walking to major attractions like the Pantheon and Trevi Fountain, and a bus stop is right around the street for further locations.
The apartment is small and modest, but we spent all day out sight seeing and it meet our needs. Nice TV for watching Gladiator before your Colosseum tour!
Keep the windows open at night in the summer. The market shopkeepers will start wheeling the carts past the windows in the early morning so then you’ll have to shut the windows. Very close to the local market.
