Excellent location - an appartment with has been freshly renewed to a perfect condition. Directly at the beginning of St. Catarina where it's more quiet. Every attraction of porto is reachable in a few minutes walk.
Service of Tripas-Coração is very personal and helpful. Very fast respond.
Hint: Be sure to visit the small port wine shop at the corner opposite to the flat. The owner speaks english very well and can help you to find right port wine.
muito obrigado !
