Great location. Rooms were nice but inside lock was broken and there was no shelf in the shower so soap had to be stored on the floor (??)
The biggest issue by far was communication for entering the building. EACH time we entered, we had to prove we were guests of Hotel Charlie, it was completely unclear what type of document to show (sometimes passport, sometimes booking info, sometimes just our name). It could take up to 15 minutes (!!) of the doorman taking our documents, going inside, coming out again, looking at something else going back inside, etc. Also they said the doorman would be there 24/7 but about 30-40% of the time there was no one, and then you had to press a button and someone would speak to you in Portuguese so it was impossible to communicate if you do not speak the language. Sometimes no one was there and we had to just wait outside for long periods.
I would highly recommend they put in a clear identification system. This was particularly difficult as we didn't speak Portuguese. Do NOT recommend, this was a horribly frustrating experience on a business trip, that stressed out our team.
Also they do not clean your room or get any new towels unless you pay an extra fee and you can only pay with a Brazilian credit card. The room was clean when we arrived but staying a week with no cleaning service is disgusting.
