We stayed at Pina's place for four nights during Christmas period and absolutely had a blast. Her place is immaculate, clean, and located close to the metro station. Pina and Marco (her son) are the best hosts you could ever ask for. They met us and the train station and welcomed us with a drink at local cafe < Italian coffee is always good :) >. Pina explained in details on Rome's local attractions, places to get good food and coffee, provided map and a lot of informational brochures. She went all the way by even providing drinks at the refrigerator, cake, and even local cell phone to make our stay at Rome very enjoyable. Thanks Pina and Marco for showing a truly great hospitality during our stay. I'll definitely be back next time i'm in Rome!
