This is the old part of the city (althoug it as been renewed and improved), in the city center, where you will find lots of little shops of any kind, many bars with the traditional "pintxos" to eat and fantastic wines from our land. Also parks and squares to enjoy and walk all around. Always lively with lots of people in it.  If you go there, don't miss the Plaza de Navarrería or the Caballo Blanco, two of my favourite places to visit during the day. During the night you have a lot of choices. The more known streets here in the old part are Navarreria, San Nicolas street or Labrit (where they open until later).
