Large and beautiful apartment in a great location. That apartment is well-equipped and accessible (we were travelling with small children and the strollers fit in the lift). The bedrooms are spacious and comfortable, and the living room is bright and sunny. The neighbourhood is lovely and it's only a short walk to old part of the city and to the bus station (about 12 min.) There are many restaurants and coffee shops nearby, and it is 1 minute from the beach. Would absolutely recommend and return if we go back to San Sebastian (which, if you are a first-time visitor, is a really great city to explore!)
Ainara is a superhost for good reason - she personally met us and settled us in, answered every query before and during the trip very quickly, provided local restaurant recommendations, and overall did everything to make our stay enjoyable.
