Have done a self-drive safary with Okutembuka and my experience was excellent.
Romy gave us valuable advices and trustly information about all the destinations and options. Ther trip was fully customizaed to our needs with flexybility.
During the trip bookings worked with any fault, all the details where matched and we had no bad surprises at all.
I would recommend this agency with no doubth for traveling in Namibia.
