I would recommend this place to all. First off, the hosts are AMAZING. So very attentive, descriptive and helpful. One of the best hosts I have experienced.
The apartment was well located with a short drive to San Sebastian's beaches and nightlife. And well situated off the highway to drive directly within an hour to Bilbao, which is wonderful to also visit for a day. We did not use it, but there is a bus and train stop a very short two minute walk away from the front door.
The apartment itself had everything possibly needed for your stay. We were able to make great meals during our stay with their fullly equipped kitchen. The beds are comfortable and everything is clean.
I suggest to search no further and move forward with this choice. You will not be dissapointed.
