Maris is great! She accepted our request very quickly and on very short notice! We were lucky to have found such a great host. She greeted us upon arrival, and was very understanding of our arrival plans. She helped us book safe taxi cabs, and gave us great information. The place is safe, spacious, clean and close to the bustling transportation that Mexico City has to offer. We saw Teotihuacan thanks to her, and were able to feel comfortable during our Mexico City experience. I recommend and trust her a greatly based on our experience. Should we find ourselves in Mexico City again, I would like to stay at one of Profesora Bustamante's places. If it wasn't for her, I don't think we would have enjoyed ourselves as much as we did.
