As a sola female traveller , i found the location of the airbnb very safe, its in a great location of Palermo, surrounded by shops and restaurants and lights. Maximo is a trustworthy and respectful person. He helped me with any questions i had and responded and helped quickly. I also never felt unsafe in the flat, he gave me the space in the airbnb and the airbnb was also quiet, so its perfect for someone who is looking for a peaceful time. The airbnb is also clean and organised and he also gives you the subte card - card to travel around buenos aires by bus and train. I would highly recommend Maximos airbnb.
