I really enjoyed my stay at Sara's. The place was very neat and clean. The apartment is very modern with nice hardwood floors. The room had everything I was looking for.
The location is excellent for me. If you are looking to stay in a nice area that isn't touristy I recommend San Pedro de Los Pinos. Very close to the metro. A few nice parks nearby and a market as well. This is a middle class to upper middle class neighborhood.
Sara was a very nice host. She speaks perfect English so there are no communication problems if you don't speak Spanish. She was very welcoming. I recommend staying with her.
