Stefanakis cancelled our house 2 days before our vacation, and offered a few worse options as alternatives.
He misrepresented them by claiming they were originally more expensive for instance (they were not).
The house offered in place was horribly dirty, the previous guests were still in when we got there, the beds were too small, most rooms lacked A/C, and the location was far away from all Rhodes' main landmarks.
Luckily for us one of his employees was extremely helpful in moving us to a better house that partially solved most issues, albeit also introducing new ones (house too small, no A/C in one room, shaky electricity).
We wasted one day of vacation and stayed in a worse house, but Stefanakis refused to change the order to reflect the new price, and kept the old, more expensive one.
