The apartment was perfect for 2 couples (but note that one bed is a single that can convert into a double). It's in the Gros neighborhood, which we actually enjoyed much more than Parte Vieja. It's a 2 min walk to the beach and 10 min walk to Parte Vieja. The apartment was clean and updated with modern fixtures, WiFi worked well for us to work remotely, and the kitchen was adequate for simple cooking (plus it had an espresso maker!). You have to check out Bodega Donostiarra -- best meal of my entire trip in Spain!
