I loved the location of this apartment. It is extremely easy to get to from the airport on Metrobus, linea 4. The bus stop is steps from the door. It's in the historic center and less than 10 minute walk from the Zocalo, where you can take one of many tour buses to different destinations (hop-on hop-off as well as guided tours).
The room is small but very charming. I recommend that light sleepers bring ear plugs, because the city is alive and noisy, but you will want to keep the window open. I actually loved the music and laughter until late at night. It reminded me that I am not in the boring Chicago suburbs any more.
Marco and his girlfriend were very warm and welcoming. Both of them speak good English, which was very helpful. They made sure that I knew where I was going and offered tips and directions. They took the time to talk to me, even though I was there during the busy work week.
I felt safe and cared for and enjoyed my first visit to Mexico City. Thank you!
