Raquel and Joseba were wonderful hosts, and their apartment is the perfect place to explore San Sebastian. Joseba made the whole check in / out process very easy, especially as our flight in was delayed, and accommodated our bags after checkout until our taxi arrived.
The apartment itself is well laid out, and the fridge was generously stocked with milk, eggs, beers soft drinks and other provisions. There were plenty of clean towels, and also towels and chairs for the beach. The only thing I'd change would be the mattress as I like a very firm one - everything else was perfect.
The apartment faces an inner courtyard, and is very bright and quiet. There is lift access without steps which was perfect as we had a buggy. There are plenty of green grocers, supermarkets and wine shops nearby for getting provisions and the apartment is only a three minute walk from the pintxos bars of the old town. Both beaches and the promenades are also very close if you're going for walks or to the beach, and there are ample bus connections only a few minutes away. Raquel and Joseba had kindly left a list of their favourite bars and cafes, which was great for helping to pick which of the many bars to go to!
All in all I would highly recommend the apartment (and the hosts!) for a wonderful stay in San Sebastian. I'd definitely stay again. Thanks for a great trip!
