By car Tarragona is just an hour from Bed & Breakfast Mas del Rey. The city is not as well known as Barcelona or Valencia, but really worth a visit. The capital of the province Tarragona in Catalonia has an authentic atmosphere. The old town is very special and famous for its Roman past. The attractions of the Roman era like the Roman circus, the wall and the amphitheatre, as well as the impressive 12th century cathedral, are close to each other in the historic citycenter.
You can buy a ticket valid for two days so you can visit all the sites at ease. Apart from the described places of interest, Tarragona has everything that a modern city can offer. Shops, from somewhat alternative to more sophisticated, a promenade you could call a small version of the Ramblas in Barcelona, good restaurants, loungebars, theaters, and a museum with contemporary art.
