Eric and I had some miscommunications involving when we would be arriving in addition to the doorman apparently reporting that we had already checked into the flat well before we had even arrived in Mexico City that resulted in us missing the first night. That said, once we got in touch with Eric he did his best to straighten things out.
As to the apartment, excellent location but it might be a little hard to find for people who are visiting for the first time. Fortunately we had stayed in the neighborhood before and already had a good idea of where it was along with some of the many restaurants and bars in the area. The nearby taxi sitio at Parque Espana also makes it easy to get around town plus it's a relatively short walk to the Sevilla metro station.
Agree with the other reviews about the upstairs neighbor being noisy. We were awakened very early in the morning by the sounds of creaking floor boards as they were walking around.
