I stayed at Columba house for 4 night in August, the week after Semana Granda, after travelling in other places in Basque Countries.
i had the opportunity to discover the village: the beaches are very near to the house, and overall if u don't want walk u could take a bus in the near streets.
San Sebastian has a very good public transportation, also at night.
In these 4 days I surfed (playa de la Zurriola), I had relax, I eat "pintxos", and tried the famous nightlife.

The room is perfect for single traveller. The breakfast is tasty, always served on terrace, with a magnificient landscape.

Columba is an excellent host: she is open to know other people and their cultures, she is friendly and positive person.
she advices u for every activities u want to do.
she is unique. in other words..she is Columba!
