My favorite thing about this place, is that you get direct sunlight all day.
From early morning to mid-afternoon you have sun in the kitchen area, then you can catch it from the balcony until sunset. There are no tall buildings around, so you have a really nice view from both sides of the apartment. There are lots of different types of trees surrounding the area. During summer and early fall everything around looks very green.
I find the apartment being very strategically located. In less then 10 minute walk, you'll be in the heart of Palermo Hollywood. If you walk the opposite direction, you'll arrive at the Dorrego Linea B station on Avenida Corrientes in about 7 minutes. There are plenty of bus stops close by the apartment as well.
The internet connection is fast and reliable. There are plenty of laptop friendly working areas around the house.
The kitchen is well equipped. My bed was very comfortable. There's a cleaning service once a week for the common areas, which I think is a great addition. Mario is a great host, very responsive with e-mails. His mom and dad are very nice people. I stayed at Mario's over 3 months, I think it's perfect for longer stays.
