Karla's place was perfect for my one night in the city. I felt safe in the neighborhood and in her building and apartment, and the location was perfect to meet up with my friend to walk, talk, and eat near the zócalo. The room and bathroom were clean and comfortable. Karla was very responsive ahead of time and welcomed me into the apartment at night, making it all very easy. I'd definitely stay again if I needed a place in the city.
