I returned from an NCL Cuba cruise and used FerTours. Below is my review.
I booked FerTours prior to my arrival through email. Fernando was prompt to reply. We booked an all day and evening tour. We had a classic convertible for the day tour. Our driver and tour guide were lovely and they wanted to provide the best experiences possible. We went outside of Old Havana first and then left our driver and took a walking tour of Old Havana. We went back to our ship for 2 hours and then we were again joined with our guide, Zulia, and we met by another driver in a closed classic car. We went to the canon firing and then the Tropicana. Our guide left us there, but the driver remained, waiting for us until the end of the show to return us to the ship. Everyone was reliable, prompt and friendly. Lovely day.
