The house is very well located, close to the metro Gloria to go easily to the beaches, close to lapa to party at night, close to Santa Teresa for the amazing views, close to the center... The room is very confortable and has TV, double bed, big table, closed and balcony and wifi. At the street floor there is the cultral center when happen many activities during the week as capoeira angola, yoga, african dance, theatre, cantombe...). You will have 3 capoeira angola lessons for free!!
This area is quite nice, "familiar". Nothing happen to anyone around the house but you still need to be carfull as you are in Rio.
The metro Gloria is very near, just check on (Hidden by Airbnb) map, to go to barra, I think there will be buses during the olypics as the house is very central, and to come from the international air…
