We had a great stay at one of Ralf's appartments in Buenos Aires (the Sky Loft). The place was even better than it appeared on the pictures, the accomodation and helpfullness of Ralf and his co-workers was more than we could ever have wished for. Ralf really goes "all the way" to make your stay the best! We recomend this host to everyone, and will definetly book with Ralf again.
