Absolutely! I lived there for a few years and it's a beautiful city with lots to explore. If you can find an apartment near Playa de Riazor or Playa del Orzán, your better half can walk to:
- Museums such as the Domus, the Museo de Bellas Artes (fine art museum), the Casa das Ciencias, etc
- The aquarium
- The Torre de Hercules lighthouse
- Cool parks like Monte de San Pedro
- Plaza de Maria Pita and the historic center
- The beaches of Riazor and Orzán
- Plenty of shops, cafes (be sure to visit Pandelino!), and grocery stores
There's an ocean walk of about 15km, called the Paseo Marítimo, which links many of these attractions on the peninsula. The historic center is just a short walk inland.
