Alejandra's place was perfect for my month long stay. Everything is modern, nicely curated, and clean. The large sunny and green patio was amazing and I'd highly recommend anyone staying to take full advantage in the morning through early afternoon. Location is great as well with plenty of healthy food options or you can go full on with a deliciously greasy torta just around the corner. Compared with staying in other parts of the city, Condesa is definitely quieter and Alejandra's place is located in a courtyard off from the street so you'll rarely hear a car (I enjoyed waking up to chirping birds every morning).
I would absolutely love to return!
