We had a 2 night stay with Carolina & Sebastian - nice couple and a lovely apartment, quiet, in a good position for walking to major tourist attractions, and only a 10 minute walk to shuttle bus to airport. The 2 restaurant recommendations they sent us to were excellent, as was the overall advice on their city - wish we could have stayed longer. Would highly recommend for anyone staying in Barcelona. Thanks Caro - hope to see you over in Australia some time - you'd be welcome in our home anytime. Cheers.
