My wife and I planned to stay at Ralf's Marilyn apartment for a month but because of change in our plan could stay only for 25 days. We enjoyed are stay very much. The apartment is a good size studio on the 15th floor of a 33 modern building. The security in the building is excellent is is immaculately clean. The apartment comes with fully equipped kitchen. It has a balcony with a very good view of the city. Once a week the apartment is cleaned and the linens are changed. Location is excellent. Very close to underground subte and many buses. Within few blocks of the apartment there at four supermarkets and bakeries. Palermo Soho is gastronomic center of Buenos Aires and you will find many of best restaurants in the city. But best of all the service we received from Ralf and his associates. Despited 13 hours flight delay, they met us at the air at midnight and showed us the apartment with throughly. The two times that we had minor problem with working of television a staff member came to the apartment with 30 minutes of our call. I short, we recommend the apartment highly and would stay there if we revisit Buenos Aires.
