We had a great experience in BA and Cesar's apartment was a great place to call home during our stay. It is a small apartment as is typical for the region but it had everything we needed. We were greeted by a friend Karina who gave us a small tour and insisted we have coffee and medialunas while we waited for the apartment to be ready for us. We arrived early but were immediately treated like old friends. Cesar arranged a cab to pick us up from the airport and everything worked well. I felt like this was a good distance from the hustle and bustle of downtown. Easy transit to areas of interest and plenty of restaurants at plaza congress to keep you entertained and full. Enjoy your time in BA.
