A lot of reviews are in Portuguese so I will be writing in English for anyone visiting Rio de Janeiro from abroad, because this place is worth the booking.
First off, location is excellent. A few minutes from a supermarket and a pharmacy, another few minute´s walk to the beautiful Quinta da Boa Vista park (and zoo), and the São Cristovão metro station. Very close by is avenida do Exercito, where you´ll find bus stops to carry you throughout the city.
The place is beautiful, spacious, and safe. Common areas are well kept, perfect to relax in the sun. Keep an eye out and you´ll spot local wildlife without even leaving the place : kitties, birds, possums, monkeys! Room is very cosy, lots of privacy and quiet. You´ll find some equipment and supplies once inside, including hygiene and a little first aid.
There is WiFi, a TV (it´s a smart one, so you can access Netflix or YouTube if Globo isn´t your thing). There are outdoor fans, and indoor the AC and fan will keep you as cool as you need to be.
Cooking-wise, you´ll have your own stove and a churrasco (BBQ pit), a fridge-freezer, equipment and utensils. When some equipment wasn´t on hand, Mauro and Rosangela were happy to provide it.
Feel free to ask Mauro and Rosangela for anything, they are truly lovely hosts and will help you out if you need anything. Rosangela´s baking is awesome, and when my flight was cancelled last minute they both helped me out. Even though I don´t speak Portuguese very well and I´m a little shy, Rosa and Mauro were friendly and welcoming, and had plenty of tips and compliments.
Overall, the booking was worth it! Obrigado Rosa and Mauro!
