This was easily one of the best AirBnBs that my wife and I have ever stayed at! The location was great: awesome views, close to the beaches, San Sebastian/Donostia,, and Bilbao. Aitzpea was so nice and so helpful! She even helped us with figuring out how to pay our parking ticket! The breakfast served in the morning is top notch and I highly recommend a bottle of their house wine.
On a side note for business travelers, my wife and I were on a "working vacation" during our stay and the wifi was good but sometimes spotty. This was easily compensated for by the amazing views of the vineyard and bay from our "desks."
Overall, we HIGHLY recommend!
