Carlos is a great host. He met us when we arrived late in the day and spent time helping us get oriented to BA. His apartment is in an ideal location for seeing the city. When we had a problem with the air conditioning, Carlos was very responsive and offered us another accommodation for the night. On the day we left, he made sure we had a taxi arrive to take us to the airport. We needed one big enough to hold our luggage (we are a family of four traveling for 7 months). I would stay here again or in another of Carlos' apartments, and will recommend him to friends and family.
