My recommendation would be to rent a different apartment if you are able to. This apartment was very disappointing.

Although the photographs are accurate there are things that photographs can't tell you and which are omitted from the description:
1. The apartment backs onto a favela and we were kept awake every night except one by loud parties going until 4 and 5 a.m.
2. The area is not safe. Two of our party were mugged at knife point, losing money and phones.
3. The bedding is very old and doesn't fit the beds properly. It quickly becomes untucked and wrapped around you. The pillows are the most uncomfortable I have ever experienced.
4. The wardrobes smelt musty and clothes left in them soon smelt the same. There was a damp feel to the master bedroom which was impossible to air properly.
5. For an apartment which sleeps 12, two sets of keys is limiting if the party doesn't want to do everything together. There were only 5 in our group but we still found this limiting. The concierge would not look after keys.
6. Finally, and worst of the lot, we nearly lost our final day site-seeing because the owner changed his terms on us at the last minute (something we only chanced across checking emails). When booking we were advised check out was flexible - ideal with a 2315 flight home. At very little notice we were told we must check out at 1130. Very poor indeed.

Rio is a great city, well worth visiting but pick a different apartment to stay in!
