The studio is great value for money (which was hard to find during the World Cup days in Rio). It is comfortable and clean. Kitchen is quite small but adequate if you want to just make hot breakfast or a plate of pasta. Also there is no Wi-fi in the apartment which can be pain in a city like Rio. We spent half a morning trying to get ourselves a local connection so that we could have data.
The studio is smack in the middle of Lapa which is the party district of Rio. It is therefore perfect if you want to party at night. But if one is a light sleeper than the noise is going to be a problem. There is nothing that can be done - this seems to be the feature of flats in Lapa. We were not terribly bothered by the noise but is quite loud.

There was also no hot water in the bathroom but this wasnt such a big problem given the weather.
