I can't speak more highly about our stay at Andrea's apartment. Andrea was the perfect host - she got the place ready for us earlier than expected so we could check in as soon as we arrived in San Sebastian and sorted out our parking at no extra cost.
The apartment has stunning views over the city, and was in such a great location for walking around the town. It was stocked with everything we could need, and we particularly enjoyed eating croissants and pastries, which Andrea had left for us, on the balcony on our first morning there.
San Sebastian itself is a beautiful place (even during a thunderstorm!) and I would definitely recommend both this apartment and the town to anyone looking for a weekend away with a partner or friends.
