Mariann is a great host who takes care for what you need and responds immediately. Mariann's place is a modern, clean-white appartment with all conveniences you would expect. On the negative side you might feel disturbed by the noise coming directly from the nearby highway. On the positive side you will enjoy the swimming pool on the 10th floor (especially with children) with some interesting views on Buenos Aires. It is a good place to stay for some days.
