We are going to Tangiers and want to know how far is your hotel from the Ferry? Do you offer Shuttles to the Ferry?
You can get a taxi from the center of Tarifa to Dos Mares for around 15€
It's about 15 minutes drive to the port i don't know if they offer transfers
The hotel is just 15 min. by car from Tarifa, maybe less. They do not offer transfers but could eventually organise a transportation for you. Ask reception.
Dos Mares is just outside of Tarifa. So not very far from the ferry terminal. I don't believe they offer ferry transfers but you would have to ask at the desk.
If you can go for more than a night I highly recommend it. It is super relaxing especially after the crazy souks in Morocco.
