Great Apartment - very clean, comfortable and well located - 15 mins walk from Train/Bus station, close to Bars and beach in GROS, and 20 mins walk to the old town. Masa y Borja were great hosts, communicating quickly with the apartment exactly as presented.
I thoroughly recommend a visit to San Sebastian - a great city on the beach, friendly, clean, great food wherever we went, unpretentious, surfy vibe in Gros, fantastic walks. We particularly enjoyed the rustic reggae bar on San Telmo, the bars and restaurants in the old town below San Telmo, and our Kayak trip out to Santa Klara Island.
