My husband and I loved our stay at Hector and Luci's. The apartment is spacious and full of natural light, on a quiet street in Coyoacan, just steps away from the walled Viveros de Coyacan park where we walked the 2.2 kilometer path -- along with many early-rising neighborhood residents -- at 8 a.m. every morning amid the green trees and cool air. We were working remotely for two weeks, and the wifi was very fast. The apartment was spotlessly clean, and Luci graciously arranged to clean our sheets after the first week (and brought us a gift of local organic bread, much appreciated!). We cooked most nights, and the high-end La Comer supermarket is a 15-minute walk and has everything you need.
In the evenings and on the weekends we loved walking to Coyaocan's main square (about 20 minutes away) to enjoy the lively scene of residents talking, walking and enjoying the beautiful weather. Within a few blocks of the apartment there are a number of very nice museums and cultural centers -- many with beautiful gardens -- including the Museum of Watercolor and the Casa de Cultura on Francisco Sosa. This is a residential neighborhood, so the pace is calm but there are still plenty of excellent restaurants and shops (great coffee at La Mano right around the corner). We also enjoyed a trip to San Angel for the Bazar de Sabado -- if you love art, many of the artists in the plaza are quite good -- and the Estudio de Diego and Frida is much more low-key than the Casa Azul (also highly recommended) but nice to visit.
This review wouldn't be complete without noting how much Luci made us feel welcome and at home. I couldn't recommend this location more highly!
