My wife and I spent two nights in this restored Tudor house in a very safe neighborhood close to La Candelaria and La Macarena (<10 min by taxi and <8,000 pesos per ride, ~$3).
The room was clean, and the bed was very comfortable. The house is big with a large living room where we received friends before heading out for dinner.
The hosts, Catalina and Camilo, are very friendly and helpful. They make the best breakfast! In addition, they helped us make dinner plans and arranged our taxi ride to the airport.
Overall, we had an excellent experience, and would stay at Serie 1948 again.
