If you want to be ideally located in San Sebastián look no further than Nora's apartment!! Within minutes from the apartment you can find the shopping precinct, the beach and bars, restaurants etc. Many of the sights are also within walking distance.
The apartment is very pretty, clean and bright. Just be aware there is no air conditioning which wasn't a big problem for us and may not be because San Sebastián doesn't get so hot. But on warmer days it might get a little bit uncomfortable.
Nora was a delightful host, she was very flexible with arrival time which we were so grateful for as we ran very late and she took the time to show us the main attractions on a map and gave us her recommendations for the best pintxos bars in San Seb.
I would definitely recommend Nora's apartment!
