We had an excellent stay at Thomas' apartment in Born. The apartment is in the perfect location, in a very hip and lively neighborhood, walking distance to shops, restaurants, the metro, the gothic quarters and the beach. Inside is lovely, with a big kitchen and beautiful rooftop terrace.
Some tips about the apartment: you have to go up 6 flights of a very narrow staircase to get to the apartment so make sure you are okay doing that several times a day. The master bedroom is open to the rest of apartment, so if you are staying with other people, be aware that you won't have privacy. There is a washer and dryer, and if (like us) you decide to do some laundry before going to your next destination, be sure to do it early because the washer takes almost 3 hours to run its cycle.
Overall, we enjoyed the apartment very much and would love to stay there again.
