We just got back from a week at Renata’s apartment. The location is absolutely perfect -- we had everything that we needed right at our doorstep! Heloisa was the host who communicated with me and she was extremely responsive and helpful! Check in and check out were very easy, as well. If you are visiting Rio and plan to spend most of your time out on the town or at the beach, I would recommend this apartment because of its excellent location and because of Heloisa's excellent communication prior to, and during, our stay.
We did find that the apartment was a bit more run down than we had expected based on the pictures. I mention this to prepare future guests. Also, we were made to pay a surcharge for the Christmas to NYE period, which I found out about after booking the apartment for a lower advertised price. For the inflated "holiday" rate, I didn't think the apartment was a good value because of its condition, particularly when compared with other apartments available on AirBnb for about the same price. However, if the apartment is available at off-season rates, I do think you will be happy staying here.
