Timothy's place is short walk from Copacabana beach, and we had a lovely stay. He was very helpful in suggesting places to check out and responded quickly to our questions.
Heads up, it's not a large apartment & while should be fine for most couples, larger groups may be a squeeze.
If you're looking for a place to rest in between seeing the sights and want to be near Copacabana beach this may be a great fit for your needs.
