I had a great stay with Kristin and her boyfriend! They were both very welcoming and gave me lots of tips on what to see and do. I only stayed 2 nights with them but my stay was perfect; the flat is located a bit up in the hills but you can reach Gloria metro with a pleasant 30 minute walk; alternatively I believe there are buses nearby, and there's always taxis and Ubers. The flat was very comfortable and sunny, with a nice balcony. It was very calm and a great start to my travels in Brazil! Obrigada Kristin, ate a proxima! :)
