We stayed for a week, Elsa was very responsive and gave us all the info beforehand, so the check-in process went super smooth. The location is great, on a quiet street in Condesa, felt totally safe, you have restaurants, coffee shops and an Oxxo a minute away (we liked Saint for your morning brew and a croissant/sandwich, just on the corner, on the other side from a quaint bookshop). The apartment was clean, a bit on the smaller side, but for a couple like us it was perfect and you really have all you need - kitchenette (with all the utensils, microwave, teapot, cups, glasses etc.), safe, towels, extra blankets, even a small heater. We appreciated the TV being connected to Netflix and other channels (perfect after a day's walk visiting CDMX). The only downside was that at times we had loud neighbors coming home at 2am (probably other tourists) slamming doors and making a bit of a racket. Nothing we couldn't survive. Highly recommended!
