I had a wonderful experience! Maria Florencia and Max are lovely hosts and they helped me with everything I needed, including borrowing me clothes the first couple of days since my luggage did not arrive with me!
The house is really beautiful, with a refined old-fashioned style and warm colors, very cozy! A bit cold, but there were convenient heaters in my room and restroom so I got a perfect temperature where it was needed. The restroom is shared in principle, but It was practically always free, almost like to have a private restroom. The location is fantastic, in the pretty Palermo neighborhood, with places to eat all around and shops, and well connected by public transportation. If you go to Buenos Aires, I would really recommend this house, especially if you love tango... I went to see Maria Florencia's orchestra playing and has been an incredible performance!
