We come to Rio quite often and this was our favorite Airbnb. The location is perfect - next to the train station, short walk to the best beach location in Ipanema, little walk to Copacabana, close to all bars and restaurants we usually go, short walk to multiple supermarkets, pharmacies and bakeries. Not to mention the events on General Osório square ( street market and artisan fair).
Besides the good size bedroom, it also has a nice, spacious and funcional living room so you don't need to be restricted to the bedroom all the time when you are back from the streets.
Finally, the washing machine makes a big difference as we were staying for a a whole week and we hated being ripped off by the commercial laundries last time we were in Rio (and they shrunk our clothes).
We have been with Jan twice and both were great stays. Looking forward to the next one.
