Nice and cozy place, extremely close to Copacabana beach (like literally 2 minutes). Safe area. Plenty of restaurants and grocery stores.
It gets a bit warm at night but there's bot a ceiling fan and AC so it is not an issue.
Only unexpected thing: There were only 2 elevators working out of 4 and so sometimes it took a good 5 minutes to get one (there are 13 floors to serve).
Overall I strongly recommend the place!
