We stayed at Gerardo's appartment for a month.
It was important for us to have a quiet place with a good internet, yet close to the tousitic attractions.
Even thought the building is close to the avenue, the appartment faces the other side and it was quiet enough and not noise with the cars from the street or from the neighbours, that you can even hear birds singing.
The flat is clean and with everything you need.
Upon arrival the internet was not good enough, but Gereado fixed it with the provider within an hour.
Another daily life needs I would mention is that Gerardo arranged water delivery, cleaning upon request and was always available for any questions or arrangements we would ask (e.g. the teapot got broken and was replaced with the new one, once we asked for).
The appartment has a good location with the walking distance to Roma Norte, Juarez, Reform and little bit further to Condesa. There is a fruit kiosk around the corner and supermarket in 3 blocks, restaurants nearby.
