I was a solo traveler who stayed in Carlos's place for 4 nights. His apartment is very centrally located and I found it easy to explore many neighboring areas such as Polanco, Roma Norte, La Condesa, and Zocalo (the historic center area). The apartment itself was very clean and comfortable. Carlos was very responsive and made sure I had everything I needed during my stay. I would recommend his place to anyone traveling to Mexico City without hesitation.
