Danny's place was great! The appartment was small, but perfect for me and had everything I needed. The best thing about it is the location. It's literally 3 min walking distance from the Copacabana beach, there's a 24h open restaurant across the street (great food) and the metro is another 5 min walk.
Mark, his friend waited for me at the appartment, showed me around and gave me useful tips for my stay. The communication with Danny was perfect.
I would definitely stay there again! Tanks Danny and Mark!
