Great stay. The view really makes this place, plus the solid, quality build of the huge block (someone said former hotel which makes sense). We had everything we needed in a perfect location and would love to return now we know where it is. Great for plane spotting as you can see San Sebastian airport (could be too noisy if you are sensitive).
Communication was a bit patchy with Britta, then another person took over which was better but check-in was a little challenging (not in-person as stated but lock box) and took us some time to get the right entrance, figure out parking and find the apartment. We requested linen as the listing says 'on request'; not sure if linen would normally be provided or not so perhaps best to ask.
