Are you still running in October? What are the nearest hotels?
The address is Turmares ( links not allowed on this site!! )
The hotel that I would prefer is called Misiana but there are plenty on the booking websites.
Take care as some listed are a long way out of town ( unless that is what you want!) Tarifa is a popular spot for watching bird migration in September and I guess that may last into October.
Get quick answers from Turmares Tarifa staff and past visitors.
