I just spent 12 days in mexico city on business and used airbnb for the first time. My experience was outstanding and I would definately stay at Mireya's place again - the experience was seamless and I felt at home - from the welcome fruit, water and cookies and small touches it made this so much better than staying at a hotel. The location was perfect - lots of restaurants, starbucks right at your front door and I was able to walk to several of my meetings at plaza del angel. I am in mexico city on business frequently and would definately stay at Mireya's place again.
The only thing that was not clear to me was how to gain access - which is very convenient - there is a guard at the entrance who has the keys and elevator access card.
