The apartment is very modern, stylish, perfectly clean and very conveniently and centrally located (it's in Gros but a few minutes' walk from the old town, Casco Viejo). There's a dedicated parking space, which, being this close to the old town, is also a big plus.
Patxi is a wonderful host who would make sure that we had everything we needed for a great stay in San Sebastián, and would supply us with a lot of great local recommendations. Communication was great and Patxi was very responsive.
I highly recommend his place for a stay in San Sebastián.
