Baixa and Aliados: flat, central, metro below, sights downhill
The Ribeira is the prettiest base, but everything else is uphill
Miragaia: the quieter riverside, flat quay walks, Tram 1 at the door
Cedofeita suits a second visit: flatter streets, galleries, locals
Gaia: the view back over Porto, port lodges, usually lower prices
Foz and Matosinhos: the sea and quiet nights, a ride from the sights
Add €3 a night tourist tax; all seven areas compared in the guide
