Jennifer is an excellent, nice host and the space is really stunning. Santa Teresa, the neighborhood, is a quiet, cobble-stoned area perched atop a small mountain that overlooks the center of the city.
It bears noting that while you do have the entire apartment, you are still right next to the apartment of the hosts. This never actually comes into play because you are completely independent, but is worth knowing in case it matters to you mentally.
I had an incredible stay nonetheless. The sun hitting the hammock in the morning as you look down on the Centro area is an ethereal experience. I wish the same enlightenment for all and could not recommend this place more :)
