The location in Madragoa/Santos is excellent, restaurants and bars in vicinity. Keep in mind that you have to climb up steep hills in the area.
It's quite noisy in the streets at night but with windows closed and AC on you barely hear the noise.
The bed is probably not the best for guests with back problems, quite soft mattress.
The apartment is fully equipped and furnished, the small kitchen is enough to prepare simple meals. Kettle and capsule coffee machine provided. There are ants around but you can find repellent in the kitchen. It's an old building, you can't do much against the ants.
WiFi is fast and stable, TV is provided as well.
Biggest setback was that I couldn't check in at midnight as agreed because the apartment was not cleaned. Found a solution with the host but it cost time and was quite unnerving at that time of the day.
