Hi, the service you listed below is a good service and I have used them befiore. If you want, contact them directly to make your reservation. Or you can make your reservations directly with me. Just tell me the dates and times that you would like and I can arrange the taxi transfers.
The email of my assistant is casas.bestcubaguide@gmail.com she can handle the arrangements. Just email her.
Or, you can just email the taxivinalescuba.com website. I know them and they are good people too.
take care,
mario
