We loved our stay in the apartment in El Born. Just steps away from shops, many, many great intimate places to eat, sights to see. Short walks to the zoo, park, museums, cathedrals, waterfront. We would definitely stay here again. Yes the stairs are noisy - no problem for us. - OH - to have the funds to just return. I'd do it RIGHT NOW.
The owner, Marc, was promptly responsive to any questions and one of the helpers (Carmen) was able to meet us a few minutes earlier than we planned. Very helpful.
One other person mentioned a wonderful restaurant and I will endorse it again. "ARTESANS", (turn right as you exit the apartment, turn right again and it is on the left). Beautiful, awesome food, good prices, beautiful interior with vaulted brick ceiling. Look it up on-line.
