I was happy to stay at Danielas's place as the first start of my life in Roma. It is located in safe residential area but everything you need is within a few minutes walking distance such as supermarket, laundry place, bank, cafe, restaurant etc. About10 min walk to/from metro stop, and there are some bus lines going to center, and bus stops are only a few minutes walk, but you have to be patient to wait for the bus!!
B&B is well equipped, and common area are very spacious so I felt like home and comfortable. Daniela doesn't live there, and sometimes it is not easy to communicate in English, but we well managed at the end!, Daniela responded quickly whenever I ask something.
