Ruy is such a PHENOMENAL host! I had to book an airbnb in BA before beginning my semester studying abroad and he made the experience completely stress-free and enjoyable. He had helpful suggestions about where to (and not to) go in the city and even picked me and my friend (who wasn't even staying in one of his places) up from the airport. He takes such great care of his guests and I could not recommend him more highly. You will not be disappointed.
