My husband and I are considering retiring to Portugal for awhile and we're planning another trip this February/March to visit places we're interested in. We're focusing on north of Lisbon to Viana do Castelo.. Does anyone have any input on the following cities/towns? Obidos, Nazare, Caldas da Rainha, Coimbra, Leiria, Braga, Guimaraes, Porto and Viana do Castelo. We want to be close to the coast and have access to amenities. We're also looking at Cascais as a possibility & the Algarve is someplace we're leaning toward but want to look at all of our options. Any input on the cities we're looking at would be appreciated, thank you for your help.
