Martin's place is clean, quiet, beautiful and well located. While close to the San Telmo Market, museums, historical buildings and other sites worth visiting, it's a serene place to be because it's away from the streets, as Martin mentioned in his profile. The gas stove and washer also make things easier.
My last day in Buenos Aires was eventful because I forgot something in a cafe. Martin helped me find it and sent me to the airport on time for my flight. I can't express enough how much I appreciate his help.
