I highly recommend Carola and her beautiful studio in Recoleta. We just got back from Buenos Aires, and we stayed at her place. It looks exactly as it is on the photos. It's clean, well decorated, has AC (which is a must in BA especially during summer, and we were there at the peak of summer), and has a fast wi-fi. It's in a pretty good and safe building. I believe the doormen are there 24/7. All of them (at least all the doormen whom we met) were very nice. We didn't get the chance to meet Carola in person (since she was on vacation), but she was very responsive all throughout the process. We didn't really need to contact her as much, because we didn't really have any issues at all whatsoever. All the info we needed such as check-in info, keys, wi-fi password were sent to us before hand (in a handy dandy guide), so we had everything we needed. We had the chance to meet her daughter, Elisa, and she was awesome! She spoke great English and answered any questions we may have, including any recommendations we were looking for. We really loved the fact that it's so close to a lot of things. We just walked to the Recoleta Cementery. During times we opted to take a cab (so we can rest from all the walking we did), it didn't really cost us much, because the apartment is so close to other neighborhoods. We truly enjoyed our stay over there. We thank all the other reviewers for leaving detailed feedback here in AirBnb. We chose this particular place due to fellow travelers' reviews, and we're very grateful because they were all right! This place is a great find! We highly recommend it as well... :)
