We booked Ruys apartment in the last minute, and Ruy answered very fast, he was really helpful and friendly. The falt is in very good location, and the terrace is wonderful! We spent only 2 nights there, and it was very confortable for us. Ruy was very communicative, and always helped us if we had a question. He gave good recommendations of where to go in the city (eating or tango show). I really reccomend the flat, and Ruy is a great host!
