Penelope's place was very gorgeous, spacious and absolutely clean. I had everything in needed and she was courteous to leave coffee, juice, water and cookies for me. The communication was easy and fast. The neighborhood was a short walk to both French Quarter and Marigny and very close to main streets on south and east, if one if interested in public transportation.
The house is on the southernmost part of Treme, and somewhat gentrified, hence becoming economically diverse. I still didn't feel comfortable walking by myself late at night. But that's the advice you get everywhere if you are a single female traveler.
