We've had an awesome time in Rome with our 3 kids and this apartment is perfectly located : close to the ground transportation, direct to the main areas of the city (even walking distance for those who enjoy walking - we usually walked in the morning and came back with bus or tram at the end of an exhausting and astonishing day).
The apartment itself is perfectly clean and Davide & Paolo are so kind and helpful when it comes to check-in and recommendations. Only negative point: 2 of the bedrooms are direct over a very noisy street - we recommend to take ear plugs to ensure good sleeping.
