We loved the Lemon Tree one-bedroom apartment on Santa Fe. Marcelo gave us a warm welcome and a very comprehensive orientation to Buenos Aires. His advice and recommendations made B.A. navigation a breeze. The apartment was precisely as advertised, and included all the amenities one could ask for. The outdoor corner terrace was a special treat. The location on Santa Fe is along the subway D line, near Recoleta, between Centro and Palermo - very convenient for getting around via public transit. Ralf's team really goes the extra mile. They arranged our airport pick-up at EZE, and even stored and transferred our luggage while we were away for a couple of days in Uruguay. When next in B.A., we will be staying at one of Ralf's properties.
