Super awesome host, great ease of communication, quick responses, very helpful with advice for the area, things to do and places to eat. Maps and guidebooks provided. Able to accommodate out of office hours check in, happy to help out where language was an issue.
Apartment itself was spacious and comfortable. Clean and well maintained. Very ergonomically designed with lots of space for storage.
Should note that the street the apartment is on is very loud but this is weighed against a very convenient location one block back from the beach at Copacabana.
Lots of great little restaurants to grab dinner at nearby. Would return.
