Overall, it was good for the price.
Some accommodations weren't good though (the shower was either hot or boiling hot, and the taps always cold). The bed already had bed bugs when we arrived which left us with rashes on our bodies... But after talking to Fernanda, she said she was going to handle it as fast as possible, so if you have any questions just ask her.
Otherwise, her friend who welcomed us to the apartment was very useful and reactive if we needed any help.
The neighbourhood is not quiet at all at night, so you can hear traffic morning, noon and night. But is definitely safe, we didn't worry for our safety.
So it was good enough for a short stay.
