Lucia and Facundo are the best hosts you could ask for. I had a last minute family emergency and could not travel, but my partner did. I was in contact with Lucía, who was incredibly accessible and understanding of the whole situation. She made all efforts to ensure that my partner had a pleasant stay and whenever we had any questions, she and Facu promptly responded them.
The following was written by my partner, who stayed in the apartment: Lucía and Facu are very kind people that accommodated every issue and question I had about the city, the logistics of the building, etc. The apartment itself is perfect for one or two people. A very functional loft-like apartment in a charming spot near all the public transportation you will need. 30 minute-walk to downtown, as well. The apartment is well-equipped, gets a good amount of sun during the day and is warm at night! The bed and the shower are amazing and worth to note! This was one of the best Airbnb experiences I had and I would definitely stay at the apartment again whenever in Buenos Aires. Gracias, Lucía & Facu!
