We had a nice stay in Zestoa, well located to discover the area.
Flat was clean and as described, even the washing machine was equiped with detergent and we got on top some food at tge reception as there was a basque festival day, which we were really not aware of.
We just had one downside, which Maitane is not to blame for, as the flat is located in the center of Zestoa and we were right in summertime, seems to be the most crowded place in Zestoa from our impression, so take into account that people will sit and talk very late into the night.
But in general we would liked to stay longer.
