The apartment is flawless. Everything works, clean and it's very well arranged (everything it's kind of logic to find and well thought). I can't think in a better location: steps from Copacabana Beach (literally), 10-15 minute walk to Ipanema, Copacabana street offers services, stores, restaurants and everything you need, Uber-friendly location, all major tourist locations are near enough to have a very nice fare.
Top marks for Eneida: always responsive, kind responses, flexible with checkin and checkout, clear instructions. Specially if this is your first visit to RJ this apartment is PERFECT.
