Humberto's place was great for our stay of a little over a week with our two 7-year olds. The neighborhood is outstanding; lots of great restaurants, coffee shops, stores, etc in easy walking distance. There are metro stations on two different lines (1 & 9) around a 1 km walk away. We always felt incredibly safe in the neighborhood at all times.
Check-in was extremely easy and Humberto was quick and responsive to the few questions we had during our stay. We'd happily stay at this apartment again next time we're in CDMX.
