Ralf's apartment was fantastic! Modern, spacious and in one of the best areas of Buenos Aires. The views from the 27th floor apartment were reason enough to stay here. Marcelo, the superintendent, was wonderful and dealt with our check in wonderfully and answered all our questions promptly. The apartment is big enough for 4 people to stay comfortably, the cooking facilities are great and the amenities within the building (gym, jacuzzi, sauna) a bonus. We will definitely stay here again when in BA.
