My experience in this apartment was great. The apartment had a nice modern decor and was situated just a few blocks from Copacabana beach. The apartment was as advertised, the only two drawback were the lack of AC in the living room and there were a few small ants in the bathroom when we came that never seemed to go away completely.
Apartment aside, Fabio was really responsive and helpful. We communicated in a mix of English and Portuguese (although he speaks English well enough that there was never a need to speak Portuguese had I not wanted to) and he helped show my friend and I a good time by helping us arrange an awesome paragliding experience, providing a lot of tourist information at check-in, and letting us know where the Carnaval events were.
