Great location, very welcoming and accommodating hosts happy to feed you with local food tips. Villa Borghese is just around the corner and a must. Less known but recommended is the MACRO modern art museum. The old center is a 20-30min stroll away allowing you to see how the locals live. In case you come by car note that finding a parking in the street (host will take up the charges) is not a given so avoid arriving during lunch break.
