Very safe with 24-hour guard service, cross the street and at the famous Copacabana Beach, Metro is about 2 to 3 blocks and can go to centro or Baja da Tijuca within 20 to 30 minutes. Uber is super cheap here! Consider getting a prepaid sim card for your phone. I use TIM for foreigners, no CPF needed and my data plan lasted a month! There are other providers like: (Oi, Vivo & Claro), more expensive and could be a hassle if you are from abroad with setting up. All kinds of different places to eat from breakfast food (eggs, coffee, bread...etc.) to sucos (this is juices for my gringos reading this) to churrasco (all types of meats, picanha, mignon..etc.) it's all within walking distance. Great place to stay!
