The apartment is large, with comfortable space and good location if you want to be between Copacabana and Ipanema. However, I would NOT recommend it for the following reasons, specially the last one listed below:
a) The apartment lacks basics like a bread toaster and a microwave, and kitchen pans that are not broken or rusted, and proper table utensils and plates. When we asked for a toaster, the owner said that "maybe he can ask an uncle to provide one". Lost cause. As for the microwave, he provided a lame excuse that microwaves are not as common in Brazil (which is not true and even if that is the case, it is certainly false in a city like Rio and when you are charging 280 euros a night.)
b) The apartment needs a good coat of painting. The sheets and bed covers were disgusting. it would have been a nice gesture to provide at least a bar of soap in the bathrooms so that when you arrive at night you have some basics.
c) Windows, shutters, and window treatments are rudimentary, and in one bedroom there were blinds but no shutters. Light and noise was an issue.
d) On Fridays and Saturdays, there seems to be a recurring street party / street disco somewhere in the back of the apartment , near the favelas on the hill, maybe a 100 mts from the bedroom windows. It was impossible to sleep until 5 am.
e) Finally, on the last day the owner announced that we needed to pay 50 reals for electricity, to be handled to the cleaning lady. However, there was no explanation of how that amount was calculated (all that sounded very fishy)
We knew that our consumption was less than the allowance because when we arrived and before leaving we had checked with the concierge the electric counter and the concierge had written it down. When challenged, the owner said that the initial reading was wrong and that we probably had looked into a different counter., so he came up with a new reading out of a hat. His point was irrelevant since he was not there when we arrived and he had mandated to concierge to perform the welcoming and counter checks. In any case, even taking into account his false initial reading, the price per kw needed to derive a charge of 50 reals would have been double than the market price (which I checked on line). We refused to pay, explained why and invited him to discuss that further with AirBnB. He wisely dropped the issue.
Overall It is really a pity because the apartment has potential, but from the first impression, excuses given by owner, to the last attempt to take advantage of us , I think that people should be aware of all these before booking. Unfortunately we left with a sour taste.
Hope this helps future guests.
