We absolutely loved staying in Federico's place. Before our trip, Federico always responded very quickly to any questions. He also arranged for a driver to pick us up from the airport which was much appreciated since we travelled straight from the US. The Jewish Quarter neighborhood can't be beat. It's central to all the main sights, has a unique and poignant history with the Jewish people during World War II and has amazing food while also feeling more local than touristy. The building is gorgeous, the apartment pristine and it feels roomy for the four of us (parents with two children). We loved the view from the balcony of the neighboring buildings.
We absolutely wouldn't hesitate to recommend this place to everyone. It's fantastic!
