If you look for a definition of a place being cozy, clean, and close to a park and a beautiful cathedral with a nice, caring, and attentive host, Martin's place fits that description.
Martin is a wonderful & generous person full of goodwill and valuable information. He was always ready to help me enjoy each and every moment of my stay in Buenos Aires.
I did enjoy my stay there.
Thanks a lot, Martin.
Take good care bro~
