Martin's apartment is a lovely oasis in Buenos Aires. My favorite aspect was the quiet. It's a really quiet bedroom and living room with a nice balcony looking out back. Martin and Dana are very helpful and responsive and definitely buena onda (good people!). The bed is really comfortable. I have mostly stayed in Palermo during my times in Buenos Aires and Colegiales is a little further out but it's also easy enough to get on the subte D. Thanks Martin and Dana!
