It's one of Tarragona's must-see places. Beautiful and well preserved. It is mostly clean but there are cats everywhere, it you are allergic be careful.
There's a free audio guide with your ticket, you scan a Qr code and you can access with it with your phone. The downpart is that they don't mention that you need to bring your own headphones before hand and there are some available at the front desk but in my case, the entrance wasn't compatible. You can read the description but the experience is not the same. I recommend bringing a coat or sweater as it is pretty cold inside.
