Carlos's place is great! It's in a super central location in Juarez and walking distance to Roma, La Condesa, and Chapultepec park. The place itself is very clean and well decorated, internet was quite good, and tons of cafes and restaurants nearby. Carlos was also super responsive and communicative anytime we needed anything or had a question!
Fair warning the street below has a ton of clubs which get really loud every night and can be heard from the living room (from the bedrooms it's not so audible) so if you need a quiet place to stay there might be better options.
Overall great experience and would recommend!
