This is a nice secure unit in a good location in Ipanema. I enjoyed my stay. I do feel there were a fee details that were not clear from the AirBnB posting.
1) The building is immediately next to a favela. I found this interesting, but on weekends there is loud music until very late hours.
2) You must have photocopies of your identification for check-in. This was not stated on the listing.
3) Guests are not permitted. This also was not stated prior to booking and check- in.
Other than this I enjoyed the stay, and I think it is a good value for the price.
