Ralf lists a few excellent apartments on here and represents a premier apartment rental company in Buenos Aries. Every apartment is in excellent condition and the level of service and the entire experience working with him and his company is top notch. I would not hesitiate to rent any apartment Ralf is listing. His staff were multi-lingual and provided many recommendations on things to do and see in Buenos Aries. His company even arranged airport transfers for us and helped us book reservations for tango shows. Check In was smooth and the whole process was a pleasure.
