Hector and Karen's place is ideal for solo travelers. It's spacious, clean, safe, and close to restaurants, cafes, bars, and Parque Mexico. I had very few issues during my stay and when I had questions for Hector and Karen, they responded quickly. It does get a bit humid at times because of the poor ventilation but it's nothing urgent. The WiFi is a bit sporadic. Outside noise does tend to penetrate at all hours of the day--even with the windows closed--but it can be soothing, especially around noon when the street musicians begin serenading the lunchtime crowds at the two nearby restaurants. All in all, I highly recommend staying here.
