I stayed with David and Clarita for a couple of days and it was great. They accepted my last-minute booking and they were very nice and helpful. David help me get around Buenos Aires (it's not that easy) and they offered me coffee every morning. The building is beautiful and stylish. Everything was clean and the bed is huge. But the best thing about David's apartment is the location. I could get to most tourist attractions just walking. In a nutshell, great place to stay.
