From the first time the communication was very good, with very clear instructions on how to check in , plus Kenan/James were answering super fast.
The apartment is new - or at least the decoration is very new, with a modern style - and I stayed here for 1 month because I needed to work and at the same time I wanted to be in the 'heart' of Copacabana and close to the beach :)
One thing I would like to highlight is that, although it is on an avenue that during the day is very busy (which is good because it is literally meters away from the subway) and from many strategic points, during the day/night from the apartment you can't hear ANY external noises, so this was never a problem when working!
The apartment is comfortable, we were 2 people who lived there and I recommend it!
