Even though we hadn't had the chance to meet Dejanira in person, our communication was very smooth. The apartment was just as she listed, in the heart of Rio nightlife. Bars, clubs, restaurants are just around the corner and the street is live until the sunrise. Sometimes it was frustrating to hear music in the morning but you get used to the vibe.
On the weekends, Arcos de Lapa is very crowded and lively. People play live music, dance and chill out until the morning and it is just 5 mins away from the apartment.
The building has 24hrs doorman who were all friendly and helpful. We haven't felt the language barrier at all. I would definitely recommend Dejaniras apartment if you want to stay in a lively area.
