Guillermo's studio was perfect for our week-long stay in CDMX. It is EXTREMELY walkable, safe, and centrally located for great restaurants, parks, and bars. The family was welcoming, responsive, and gave great recommendations for local spots and general safety. Also a bonus was their sweet husky, Hades :) One thing to note: it was no problem for us, but to get to the studio you do need to climb a steep staircase.
