This is a small and cozy apartment in a quiet street close to Piazza Tuscolo, a busy and central location in the Appio Latino neighborhood. Subway is only a 10 minute walk away (S. Giovanni and Re di Roma stops are about the same distance). The apartment is at the ground floor of its building, with the windows open on a private driveway / courtyard in common with other buildings. We thought privacy would be an issue, but luckily there is a bit of distance between the bedroom and kitchen windows and the walking area, so no people snooping around into the apartment.
We spent over a week and cooked several meals in the kitchen. The kitchen counter is a bit cramped, but overall functional, and the fridge is big enough for a full grocery load (by Italian standards that is). The area has several businesses. There is a COOP grocery store literally around the corner, a neighborhood market (mercato rionale) a block away, a few restaurants, several bar caffè, and shops.
Beatrice was a great host. We contacted her a couple of times with a few requests and she always got back to us. Overall, this is a great base for exploring Rome, and we would consider booking it again in case we come back to Rome.
