Very enjoyable experience! Antonella and her husband took great care of me and were very flexible with my arrival time. I got locked out of the house the last morning, and they arranged for someone to let me back in very quickly. There is plenty of room, and they have done a great job of thinking through all the important details. I definitely recommend staying here. For those interested, the apartment is about a 10-minute walk from a metro station, and it's only 5-10 minutes further to walk to the Vatican. I had planned to take the metro, but I ended up walking everywhere.
