Cecilia's apartment worked very well for us. It is perfectly located, particularly for those arriving / departing San Sebastian by train or bus ~ just an easy 5 minute walk from the Donostia station. The apartment is nicely set-up and maintained and easy walking distance to most of the city. Cecilia was travelling for work but her sister Paula met us at the apartment and patiently explained everything for us, also providing us with a nice tip about the excellent restaurant just around the corner. Cecilia is very well organised, with good communication and a very flexible approach. Well recommended.
