Great location. It felt secure, safe. If you are looking for a place to sleep with peace and quiet, forget it. It is super noisy. Very otdated old building. Small rooms, small hallways, you hear everything from every angle. The elevator ringing, banging everywhere, tourist luggage sounds at any hour.
On the bright side everyone was very helpful in everyway. If you are going to carnival DON'T GET BOOKERS TRANSPORTATION they are a mess!!!!. The front desk offered a better option. Cheaper, super organized and reliable.
Although it was noisy as hell and the cleaning wasn't that impressive, it was worth it for the price, the awesome service and the location made it worthwhile.
I would return if I ever comeback to Rio.
