We spent carneval in Rio and chose Luis´ appartment as it is in a great location. Close to copacabana beach and many restaurants/bars.
The appartment is very big, though everything is very old. The AC in the rooms might be to loud for some people to sleep. The washing machine didn´t work( we might be too young to use those very old washing machines, but it seemed like there was no power).
The kitchen is big and offers everything you need.
Luis was a good host. He managed to have someone give us the keys when we arrived at midnight. He responded to all our mails quickly.
If you don´t need luxury, this is the place to go. Good price-performance ratio!
