I stayed at Emilio's apartment for a month and half and had a really great time! The apartment is very cozy, has natural light during daytime and has all what one may need for a long stay. The location is great. The area is very safe and quiet. Walking distance from line D and Sante Fe avenue (where you can find all bus lines) is only less than 5 mintues. It's also only 10-15 minutes walk from palermo's beautiful parks.
The neighbours are very nice and helpful, and welcomed me since Emilio was not in Buenos Aires during my stay. Although not present, the communication with Emilio via e-mail was really good. He was making sure I have all I need and that I enjoy my staying at the apartment.
If i'll ever return tu Buenos Aires, Emilio's apartment would definitely be my choice.
Thank you Emilio!
