Pros: the location couldn't be better, and the room looked like the photos.
Cons: The room is moldy and damp, & smells like a cellar. The wifi didn't work for the entire stay, and the host basically shrugged and stopped communicating when I asked about it. The TV was broken (like, literally cracked), and though that wasn't a big deal (I'm not in San Sebastian/Donostia to watch TV), it was pouring rain all day & without wifi it would have been nice to have something else to distract us. I would not ever stay in this room again.
