There is an hotel in Oporto called Hotel Paris that exists since the XIX century. It's delightful. I was there twice, each time for several days.
It's always full because everybody likes it, it's so picturesque.
Last time I went there its was full of people, even a couple from New Zealand.
This is the Breakfast Room.
It's full of corridors. Our room where here, one in front of the other. In the botton, a window with a view to the town - also our room had big windows with beautiful views.
The bedrooms and all the hotel have antique furniture.
