Our stay at Wolfgang's penthouse was excellent! Very comfortable apartment (spacious for our family of 4, well equipped, very friendly staff at the 24hrs reception, small but nice private pool area), and great location (within walking distance of Copacabana & Ipanema beaches, supermarket and small restaurants for breakfast right around the corner, safe area).
We didn't meet Wolfgang in person, but communication was excellent (fast, reliable, good advice) and easy.
Highly recommended, we definitely would stay here again!
