We had a great experience with Ralf's apartment and his colleagues. The Panorama unit was great, comfortable, and in a great location. His colleague, Marcel was fantastic. We had lots of flight cancellations and delays getting there and had to change the check-in time alot, but all was done with ease and acceptance. Marcel stayed to meet us at 2:30 AM, then stayed to tell us all about how to get the most out of our visit to Buenos Aires.
