Edificio Esperanza was for us a great location. Marcela and her Familia are very welcoming, helpful and kind people. In the Condensa and nearby Roma districts there are plenty of good coffee shops, places to drink and eat, and shop. It's 4 kilometers to The National History and Anthropology Museums. Uber service is readily accessible. Busses, too. We walked alot and felt safe, even in the early night. For a huge city, Ciudad de Mexico is shockingly clean and well kept for the most part.
Remarkably quiet place to stay. We were in the rooftop room #2. Though a small studio, it provided comfort and coziness for us for our 5 night stay. The only drawback was the frequent running and high pitch of the communal waterpump, located on the rooftops of rooms #3 and 4. As a somewhat light sleeper, it made it difficult for me to fall back to sleep. We communicated with Marcela about that.
Despite that single drawback, we highly recommend Edificio Esperanza!
