I spent 3 weeks in Osvaldo and Tamara's house and it was absolutely lovely. I loved Yungay. It is a vibrant neighborhood that felt very safe and, although it is not "central", it is a perfect place to base your stay as it is just 3 blocks from the metro and one block from many micro-buses. The room is a private studio. It is quiet and contained spacious. There are two new murals outside and they are exquisite. Be sure to visit Museo de los Memorias which is only .5 mile away and La Picada de Gloria, a classic Chilean bar close by. I can whole-heartedly recommend this Airbnb rental. Enjoy!
