I had an issue with my flight and needed a place to stay last minute (literally 8pm), so thankfully Carmen responded almost immediately and let me book her place. Carmen was a super helpful host and the room was really cozy and the perfect place to crash after long days walking around the city. There are two metro stations within a 10 min walk which means that you are only about 8 stops away from el centro and literally 2 stops away from the airport (or 4, depending on your terminal).
