Samuel was very flexible. We booked the apt for our last days in Rio, but due to flight changes we were not able to stay for a night. We did use the apt. for the afternoon to store our luggage, and Samuel was very flexible with arrival and departure. He helped us with making a reservation for a taxi etc., very helpfull. The apt is small but complete, exactly what you need for a city trip. The apt. building is conveniently located one block from the Copacobana beach. We would recommend visitors to Rio to stay at Samuels apt.
