For starters, my host Harmony was very prompt, kind, and courteous when communicating with me.
Location: was perfect. 1/2 block from Copacabana beach (north end). Many restaurants, bars, clubs, grocery stores, pharmacies, medical diagnostic center all within a 2-3 block radius. (Great burger restaurant next door to airbnb).
Remember, the Copacabana area is a very lively area (as far as noise)...(mostly during the day but a little bit at night as well).
Apartment building: has 2 elevators. 24hr door man that opens gate via remote for entry and exit. Guests will have to check-in with doorman. Easy check-in and checkout. Will need to know Portuguese or have a language translation app to communicate with door man during check-in.
Apartment: Pros: very clean (less than 24hr booking and arrival). Very nicely designed place. Bed was decent (not too soft but not too hard). Clean quality sheets and towels. Hand soap and bar soap in shower was provided. Fyi, the bum gun is powerful lol. Wifi worked perfectly...no issues. AC worked perfectly...no issues. Cons: single panel windows, especially next to bed. These single panel windows allow you to unfortunately hear everything outside. I suggest bringing ear plugs if you want to sleep in. Water temp was either hot or cold. I could not achieve a consistent warm water shower. Maybe it was operator error on my part.
Overall: this airbnb was great. 4.5 out of 5 stars. I would definitely stay at this airbnb again.
