I can't say enough about Helena's Air BnB, and I have stayed in a number of them. My daughter and I stayed here for four nights and it was just perfect for us. The pictures are pretty accurate but don't completely do the apartment justice. It is light and beautifully furnished; cozy and peaceful and well appointed and very very clean. Although one bedroom is in an upper loft space and the other is divided by curtains and off the living/dining room, my daughter and I felt we had enough privacy from one another. There is a wonderful, green porch you can sit on, with a great view and relax after a long day and it is very peaceful and private. The location is lovely since it is in Palermo which is a great part of town and easily accessible to public transportation and within walking distance to many things. If you go, have a caffecito down the street at Cafe Coco, which is lovely. There are many great restaurants in the area and parks.
In terms of communication, warmth, being welcome and helpful, Helena could not be any better. She immediately responded to any questions and concerns and had two helpers that let me in, oriented me and were also in touch to answer questions. By the end of our stay, I felt I had made another friend! :)
If I every come back to Buenos Aires, I would definitely stay here again!
