I shall be in Spain for two weeks next October. Plan to arrive in Madrid, stay 3 or 4 days and on my way to Galicia visit Segovia and /or Salamanca, then go to Santiago de Compostela and visit family in Vigo and Orense. Need advice on Hotels/Hostales in Segovia, Salamanca and Santiago:clean, safe, not expensive, with character, in historic/old area, with elevator (I am 69). In Madrid will stay in Hotel Plaza Mayor . Shall I need car or can I make it with public transportation? Can I rent a cellular phone while in Spain? Suggestions/advice will be appreciated.
