Ideal location to explore Porto. Close to the old town. Good prices for what you get. Breakfast is at the cafe next to it. You get vouchers. It's always the same you get every day and a bit limited, for example no eggs. It's not a bufet. But it's good. Bread with ham and cheese,, butter, marmelade, sweet croissant, coffee, orange juice.
The noise depends on the room beeing located to the main street or backyard.
To the back it's calm. Can recommend it. You wont be dissapointed, even when you are used to 4 star hotels.
