Juan's place was even better than my expectation. He and his elder brother were so kind and they helped me a lot. (To set up my pre-paid SIM, to show places to go and things to do in BA, etc...) The location was perfect and very convenient. Everything, such as supermarket, bank and subway station, was walking distance. The neighborhood is very safe even at midnight. Both of the room and common spaces were comfortable. Since the flat is spacious, it's easy to keep the privacy (If you need it). Thanks for everything, Juan and Joaquin!!!
