I cancelled the booking right after entering the rented apartment. A friend of the host came to open the apartment more than an hour after the agreed time. He was probably under the effect of alcohol as he smelled alcohol. Not a great experience. We ended up cancelling our stay after visiting the apartment and did not get reimbursed. I would not recommend.
Also, I would’ve preferred staying closer to San Sebastian if this is what the purpose of your visit to this town is.
