Simona's friendly agent met us and gave us a small tour of the apartment when we arrived. As other people have pointed out, you will have to sign a document, pay a tourist tax and give your credit card details. The apartment is also small (it can sleep 4 people) and some of the fixtures are a little worn but the location in Barcelona is excellent. It is located in the lively Barcelonetta area between the tourist beaches and downtown Barcelona and you have a view of the harbour. We all found it a great a base for exploring Barcelona and were mostly outdoors.
