I enjoyed staying in Natalia's apartment. It was in a newer building with good security. It's in a great location walking distance to Palermo Soho, Ave Santa Fe, and other desirable spots. The apartment itself was very clean and updated with a fully equipped kitchen and a washer. There is a sizable private terrace and the apartment gets good light. Although I didn't meet Natalia myself, the woman who did introduce me to the apartment was very friendly. FYI she only spoke Spanish. That being said I don't think anything she said would have been that difficult to interpret for a non-Spanish speaker.
