Roberta's apartment was perfect for my one week stay in Copacabana as a solo traveler! The location is amazing with lots of restaurants, bars, stores, a metro station, and the beautiful beaches all very close by. The neighborhood is busy but the apartment was quiet enough that I could sleep through the noise down below. I felt fairly safe in the area (of course you should always use common sense and be cautious). It was easy to go in and out with helpful front door staff to open the gate. There was plenty of space to put my things and even a comfy desk for working (if you can manage to actually work with the beach so close by and tempting!). The bathroom is quite small and the shower would be difficult for larger people to use, but the rest of the apartment is spacious and would be fine for two people. Roberta was an excellent host who communicated well (in Portuguese and English if necessary). I would definitely stay here again the next time I'm in Copacabana!
