We stayed at Ralf's apartment for over a month and it was the best experience ever! The location is perfect, walkable to restaurants and museums alike! The apartment is fantastic, extremely clean, comfortable, well equipped with great views from every room. Ralf and his team - Marcelo and Tomas are truly professional. They organized our airport transfer and took the time to get us acquainted with all the essentials for our stay in Buenos Aires. Building has an amazing gym, a pool, laundry and great security. This is one place we will certainly return to.
