Josefina was extremely responsive and her place was beautiful. My friend and I stayed for 5 days. We had been living in Buenos Aires for 5 months to study, took a quick trip to Chile, and returned to the city to stay in Josefina's apartment before we returned to the U.S., as our previous living arrangements had expired. The place appears as it does in photos, and Josefina leaves many excellent tips for the city. The only things I will say are that, while centrally located, sometimes Ubers (which, in my opinion, are the safest form of transport) will not enter the Microcentro area due to restrictions. Additionally, I found this area to be slightly more sketchy than, say, Palermo or Recoleta. However, the trade off is great tourist attractions within walking distance. If you are only in BA for a few days, this is ideal. Finally, the bathroom is pretty tiny, but if you are a singular guest or only around for a couple days, it's not a problem. Just something to be aware of. I would definitely recommend Josefina as a host to anyone new to the city, especially hesitant travelers.
