I stayed at Valeria's bello place for three days, and it truly was wonderful. Valeria was very helpful in providing information around the area and how to get to her place from the train station. It took me a little time, but I got there with no trouble. My room with private bathroom was very nice!! Fresh linen and towels. And Valeria has a beautiful beautiful balcony overlooking the centro Storico area. It's honestly just minutes of walk to all of the great places around. My three days were quite brief, still I managed to cover almost all the good spots. And thanks to Valeria, who let me walk her dog! It's really a cool and friendly experience to walk around to all the basilicas and landmarks with her dog during dusk :)
I would definitely recommend this place, I think especially for solo travelers keen to explore the place. The neighborhood is very authentic, I would say a bit ghetto-ish, well for someone like me, I was born and bred in a big city bright light area. BUT, people there are actually very nice, and it is safe. Cheap and Fresh fruits and yogurt downstairs, and of course, delicious pastries and fried pasta brekkie!
In the meantime, Valeria is such a kind host, she recommended me the pizza place literally like 5 minutes away from our place. And let me tell you, perfecto. And she insisted on taking to the "Eat Pray Love" pizza place downstairs, again 5 minutes walk.

Grazie Valeria:)
I look forward to coming back and staying with you again!
