Just finished my fist trip to Brazil. 1 week in Salvador, 2 weeks in Rio. I stayed in 5 different places, and the last was this one. If you're going to spend more than a few nights in Copacabana, you should stay here because the typical hotel room in the same price range will give you claustrophobia.
I read the previous reviews on this apartment and they were accurate. Yes, the street noise is there, but you are in Copacabana in a busy city! Also, Roberto is a great host.
This apartment has a huge bedroom window on the 10th floor that looks straight down a street one block to the Ocean. You definitely see enough of the sea to know, what's the weather like on the beach... is it windy? are the waves too choppy, etc. The kitchen is ample, though I only used it to cut my fruit, poor my wine. I wished I had more time to sample more things from the markets in my own room instead of the typical menus of all the restaurants.
I did take the subway one time. Roberto showed me a shortcut whereby you exit the rear of the building from the 5th floor. It's really cool as the building is on a slope, so backside is 5 stories up.
The leather couchin the living area is great. There is also a smaller love seat in leather wich are new and very comfortable.
I kept up with work from the dining area table seating.. Wifi worked just fine. For some reason on my laptop I often had to disconnect/reconnect the wife to get internet access, though I never had to do it with my phone. I was able to watch a few movies because the internet speed was very good.
One piece of advice... The bedroom has a wall a/c unit. But, if you simply crack open the bedroom window and another window in the dining area, you will get a nice breaze since this apartment is on the 10th floor.
I will definitely look to stay here again when I make it back to Rio.
