In late March 2011 I booked Ivan's House in Montezuma through Humberto at firstname.lastname@example.org. Just today I emailed to advise of our arrival time to be told that although we were sent reservation confirmations and paid for this place in April 2011, our reservations were cancelled (this from Humberto). Upon following up with Ivan, we are told that Humberto is fraudelently selling reservations for his house, and he is unable to honour them. Has anyone else had this experience? Beware! I will be contacting the folks here at tripadvisor to be alerted to this.
