We were in Mexico City in December 2011 and we stay at Francisco's apartment. He was very flexible with our times of arrival and leaving and made life for us very very easy. The place was amazingly clean and nicely furnished, and I was sad I didn't get to use the kitchen as it looked very nice.
The apartment is located one block away from Reforma which allowed us to walk to different touristy stuff and take a taxi if we needed to go somewhere else. The area was very safe and it was a short walk to corners stores or restaurants if you wanna go for dinner.
We also forgot some clothes on the apartment and Francisco made arrangements to deliver them to us. He was an amazing host, you will not be dissapointed!!
