Giancarlo arranged a driver to pick us up at the airport. I would 100% recommend this as it is pretty much the same price as a taxi and you don’t have to deal with the crowd of taxi drivers hounding you at arrivals.
Giancarlo met us outside his place and gave us a tour of the space. He let us leave our bags there as we arrived before check in time but had tours booked at the Vatican. The space is very close walking distance to St Peters and a €12 taxi ride to basically any of the other main places to see. Coliseum, Spanish steps etc.
Great restaurants are close by and the neighborhood feels safe.
I would have no problem staying here again.
