I only have good things to say about our month-long stay at Alejandro's place.
The location was great. Very convenient, close to everything you would need. And the neighborhood was really nice - a toned-down version of Roma or Condesa. Quieter, more peaceful, but filled with restaurants and cafes.
The unit was great too. It had everything we would need - a nice kitchen, laundry, a lot of closet space. Looked just like the pictures and was very comfortable. The building feels quite secure with concierge at the front. The internet access was very fast and reliable.
Alejandro was also a great host. I had a few minor questions and he always promptly replied. He also checked in a few times to see how things were going. Over all the communication was excellent.
Highly recommended!
