We were in Madrid for work and made an impromptu plan to visit Barcelona and Sergio's apartment fit the bill. He was a very generous and helpful host. He took out the time to guide us whenever we needed his guidance and was always available to us over the phone as and when. It was out little home away from home for a couple of days and we cherish our memories there. Thank you Sergio and thank your mother on our behalf as well. N look us up whenever you come down to India.
