Bad choice indeed!!! They will cancel your reservation at the last minute with an excuse, if they will find a longer and gainful reservation. That happened to us 4 friends, during the Maratona days in 2007: after they had confirmed the 1-month-before reservation and validated it even 2 days before the day of our arrival, the morning before they said with a sole E-mail that they don’t accepted us anymore and they received other customers!!! (We kept all the messages, as proof).
