I spend two nights in Porto with my boyfriend and this apartment was the perfect place to stay!
It wasn't too expensive, hence the small size of the apartment, but with everything you might need and perfectly organized!
Luis is super reactive, gives good recommendations and tries to make of our stay a good one.
However it is true that at night it is extremely noisy outside, even for someone who is used to the noise. So maybe pack a pair of earplug in your suitcase.
