The place itself was fine and the check in process very good. But after one night, we were covered with mosquito bites. In the morning, we learned there was a serious mosquito infestation in the apartment. We killed about 30 of them and bought all kinds of products to keep them away. We had to sleep with the windows closed the second night--it was boiling, and there's no air conditioning. The host never responded to any of our concerns about the mosquitoes. It's not a San Sebastian thing--we didn't encounter mosquitoes anywhere else, and the porter in the building said the building doesn't have an issue with them. There must be standing water somewhere in this unit. Anyway, for us it was a disaster as the rest of our trip to Spain we were itchy and uncomfortable. This experience cost us nearly $300 a night so we were pretty upset.
