Short review: Great location, wonderful host and place, perfect price. If its more than one of you travelling get this spot. One bedroom has a better bed than the other (one near the bathroom).
Long Review:
Location: Jamie's two bedroom apartment is super close to post 8. Post 8 is near the outdoor gym. In the mornings I would get up go for a run along the beach and workout at the outdoor gym. While Jamie's apartment has a small gym, nothing beats resting and facing the ocean. The apartment is also next to the subway station and the subways in Rio are easy to navigate, at least for this New Yorker. The neighborhood is super safe. I felt comfortable walking around late at night. We always find new places to eat and shop.
Host and Place: Jamie came to visit. He was really nice. When he wasn't around the staff at his building were just wonderful. It isn't part of the culture to tip but we felt compeled to. The front desk guy was great and he even helped with the taxi company and also when we had wifi issues.
Price: We got to Rio early and had to spend a night at a hotel. We were 4 blocks away from the apartment, on the same street and paid double the price for one room. Jamie's two bedroom apartment is on a great street and it is a legit two bedroom apartment.
