Like for casas, in Cuba there are many taxi without a license. The fares are cheaper, but only apparently as - once in the car - the driver will do everything possible to bring the tourist in a home or a restaurant (ususally licenseless) that will pay a bribe to the driver. In recent years, there were real scams against tourists, unaware, transported by the taxi driver at another house that is not that of the address provided to the driver. In other cases, at Habana, some illegal taxi driver wait with a sign written at the airport and copied from the sign of another – legitimate – taxi driver waiting, hoping that tourists will fall in the trap.
On-line reservation form is available for la Habana only.
This service is managed by state run taxi company, so you'll be diverted on another site. If you already booked a casa through CaseCuba, simply enter - in the destination address field - CASECUBA followed by the house code (e.g.: CASECUBA HAV101)
