Hello Mazuntina,
No the accommodation was not San Cristobal and we spent a wonderful week at Daniels'Brisas Marina but I found these photos which show the white building we are talking about. One show the house on the far right and the other shows it in the centre. I can't find anything online which gives a phone number or email address so we can make reservations.
If you or anyone can help, we would be very appreciative.
Thank you,
Cameorn Robertson
