Porto, for me, is a badly known town, because, staying only 2 hours distant from my home, I generally don't stay there. Not staying there, time is usually short.
The only hotel I used in Porto was this one, when it was yet called "Porto Boega".
It had the advantage of, being a *** hotel (now raised to four, it seems), its situation a little far from the center reflected in the good price, and, as I was going to the north, It freed me from the traffic congestion in the center. Good decision, and good stay.
Address: Rua do Amial 601-607
You will never find it
This is a restaurant where I think that you will never eat.
It is located in a residential area, far from all the touristy attractions, and with no particular reason to call you there.It happened that I was in the area, needing to eat in 45 minutes, and it was... there.
No complaints about the food, the timing was respected, and the price very cheap.
However, it will be forgotten. Soon!
