I can definately reccomend Ignacio as a perfect host and his house as the perfect stay in BA. Ignacio is etremely welcomming and helpful, and he is a great person who genuinely cares aboout you having a good time at his place and in the city. The house is beautifull and clean, and it has the atmosphere as well as all the necessities you need to feel at home. Even when staying in the shared room, I had all the space I needed, and I especialy enjoyed the "walk in closet" and the two patios. I was suposed to stay with Ignacio for a week (and then crash a friends place), but I ended up staying with Ignacio for my whole stay in BA, because I felt so well at home. Staying with Ignacio was my best experience in Argentina as well as my best experience with airbnb!
