Marco is extremely helpful and generous. He gave us a bottle of wine and treated us to a drink for each person staying at the cafe downstairs. (Though we didn't have time to enjoy that).
His response was very fast via the Airbnb msg.
The location is very walkable to Vatican City, just 10mins to 15 mins walk. Which gave us plenty of excuse to come back to rest our weary legs.
There is a big carrefour supermarket just 5 minutes walk from the apartment. Which settled our breakfast.
Restaurants are around 5 minutes walk out of the apartment.
The only thing that we had concern was the parking space is always full for the free and paid parking by the side of the road.
There is a paid garage at the end of the road, but that cost euro 40 per night.
Other than that, the house is perfect for our family of 6.
Will come back again if there is a chance.
