Great stay! 10/10 would recommend it. It is small but is exactly what you need for one or two people. Clean bathroom, simple kitchen, laundry, close to the metro and EcoBici bike stations (which the hosts recommended to me). There are 24/7 guards at the building who are very helpful and keep the place secure. Finally, it's close to La Reforma, Rosa, and relatively close to Condesa and Roma.
The hosts were very kind and responsive and I had a great experience. Thank you again for recommending EcoBici — was a great part of the trip :)
