I can't recommend staying in this apartment. I would not have chosen it but it was a recommendation from the host to replace another apartment that I had selected.
The location is the only good thing about it, it's very central.
Otherwise its very noisy at all times of day, the windows dont properly isolate the noise. I barely slept for 4 days.
It's very hot in both rooms, but the top room is just ridiculously hot, even with a fan always on.
The apartment does not have proper basics, even the coffee machine uses some kind of weird capsules that can only be bought in specific places (and yes, I tried 5 different capsule types).
By the way, the apartment is on Rua das Flores, 48, and not 42.
