Spent two weeks at Happy House. The house was well appointed and well situated next to a subway, several grocery stores and a variety of restaurants, bars and cafes. It is also quite central and close to Palermo Soho and Hollywood. Check in and check out was easy. The owner really took care in making my stay a pleasant one. Since she knew I was going to be working from the apartment, she even took the time to rearrange the living room ahead of my arrival - without me having to ask - so that my work desk would be well positioned next to a window. My flight out of Buenos Aires was at night, and there was absolutely no problems when I asked to check out at 6pm. The Internet is a bit slow, but still works well for sending emails and surfing the Web. I'd have no problems recommending the apartment to anyone going to Buenos Aires.
