Arriving in the evening, we waited 45 minuts before somobody totally drunk came and gave us the key.
I booked a room for 2 beds, but only one was made, I had to share my bed with my daughter. The "receptionist" didn't understand as soon as I asked for something, but he understood enough when he wanted to sell us something.
No light in the room (only 2 small beside the bed), very bad smell coming from the bathroom.
I'm really sorry because it's the main thing my daughter remembers about Porto.
