Cristovao is very quick to answer and gave me a lot of useful tips before I came.
Location is great!! It is very close to both Ipanema and Copacabana beaches.
Wifi worked very fine in the apartment all the time.
A lot of amenities in the apartment.
The bedroom is next to the window, which is not thick enough to cover the noise from the cars in the streets. So better come with your earplugs (which I always do).
