I can't recommend Mi Casa en BA and Ignacio as a host highly enough. I've been traveling five months now and this is easily the place that has felt most like 'home'! The house is beautiful, with great shared spaces if you want company & plenty of room to spread out for the days you don't. The bedrooms (I stayed in a private and the shared during my time) are fantastic and nicely appointed. Ignacio was wonderful, really easy and helpful with recommendations, figuring out which bus I'd need, sharing info about his city etc. Stay here!
