My boyfriend and I stayed at Carlos' place for 3nights and loved every minute of it! The apartment is spacious, comfortable and cool, and the art deco style makes this 100x better than a hotel. Carlos was a great host - he offered us an airport pick up at 730pm at night and provided us with maps, great tips and pointers for our stay in BA. He also promptly answered any questions for us and solved issues efficiently.
The location is great, close to a famous shopping street and restaurants.
We would definitely stay again! Thanks Carlos!
