Good stay, reasonable rate. Clean space with modest kitchen. If you plan on preparing your own meals you may find it lacking and will need a trip to the market.
Overall this is nice place centrally located close to entertainment. A previous posted mentioned the smell of cigarette smoke but I did not detect that. There was however a musty smell common to basements or other places where there has been high moisture. It didn't pose an issue and opening a window cleared the air. I gave a stars as the printed instructions say the location is "Rua da Emenda 41" but there is no building 41. The actual location is Rua da Emenda 45 which is located a corner.
If you register your ID online you do not need use the automated check-in located in the lobby. If you attempt to do check-in in the kiosk after having entered your passport info online the kiosk will give you a vague error. I recommend entering your traveler info online and skip the lobby kiosk entirely.
Also, I recommend Dear Breakfast in the mornings, it's pretty close buy.
