Pre-stay arrangements great. Rob exchanged mobile number and was always reachable by Whatsapp. I've never met him though. His help Billy was met me in from of the house and showed me around.
Apartment is as shown. On 12th floor of a big residential building, 70s style. Very central location in Copacabana 5 mins to metro, 5 mins to the beach. The "executive" bus from/to the airport or bus terminal stops 1 block away.
Have in mind, that this accomodation is pretty basic, but clean, bright, not noisy and sufficient for 1-2 people. Good security concierge, additional door code for the unit and room key. Recommended.
