An excellent option if visiting San Sebastian.
Location - is worth the money. It is in the first apartment block across the road from Ondarreta beach. So literally steps away from the beach. We in fact prefer Ondarreta to Concha as its relatively less crowded (even if you reach the beach late in the morning, parasols were always available for hire). The area itself has a bunch of restaurants including several places just downstairs. But it never gets noisy.
Interiors - the photos match the apartment. Everything looks new! The apartment is fully equipped including functioning kitchen, a large dining area, washer, two large clothes lines, etc. Four good sized bedrooms and two large bathrooms.
Parking - There is adequate street parking available a short walk from the apartment. Around 3-4 Euros for 24 hours which is very reasonable.
Hosts - are very responsive. They sent us several nice suggestions for the stay, and also arranged for an early morning airport transfer during check-out. Always a message away.
In summary, this is a highly recommended option if you are two families visiting San Sebastian - which in itself is a hidden jewel of North Spain! We cannot wait to visit again.
