I stayed at Rogers apartment for 8 days in January and can highly recommend it.

The apartment looks exactly as displayed on the pictures, is super clean, quiet (you can sleep with open windows), equipped with aircon (important due to temperatures), the bed is comfortable and the internet/wireless network is fast.
Location is great - very close to the beach, underground/metro station (ie to go to ipanema), supermarket and gym.

Roger is a very nice host who pays attention to any detail. When I arrived he provided a basket full with fresh fruits, flowers, the fridge was full with all sorts of drinks (water, mate tea, coke, beer, milk,...). There were towels, beach towels, tourist guides and maps and he gave me tips on what to do in Rio.
Also when I needed something in between my stay he was very responsive and helped me with my request quickly.
I've been to many hotels of all sort of categories and hardly any of them provided the same kind of service.

If you plan a trip to Rio - here you get real value for money (in contrast to hotels).
