Stay with Gabriela and Carlos is the best decision I have made for Mexico city! First of all, This is a real homestay, that you get to spend time with them, not to mention that they are extremely friendly, helpful and warm. Gabriela would often invite you for her authentic Mexican breakfast. During a dinner I made for the family, they played authentic 30-40s beautiful Mexican music, I totally enjoyed my stay here. I would definitely come back.
By the way, the location is in the heart of Condesa, close to many cafes, perfect for those people who work remotely.
