We had a great time with our 4 year old daughter in Porto. Carolina's apartment is at a very nice location near the Ponte Luiz I. There are two balconies. The one in front of the building facing the street with several bars,has a nice view over Porto and the other balcony is a more quiet one in the back. The apartment is really nice, spacious, well equiped and nicely decorated. We didn't need to contact Carolina for help, but the contact we had before our stay was friendly.
