Our family (couple and three kids: 9, 15 and 16 years old) had a very nice week in the flat. It is exactly as described: spacious, full of light and with nice views (7th floor). The beds are comfortable, and furniture and bathrooms are of good quality. In the house where the flat is located, you do not feel as a tourist, as you are right in the middle of a Spanish town. Small supermarket and bakery are 5 meters (!) distance, with more shops nearby. The beach (Zurriola) is 8 minutes, the old town and La Concha 15 minutes walking distance. Our language school (Tandem) was just around the corner. Parking in front of the flat is not possible, but unloading is, and the hosts give you directions for safe options, again 8 minutes by foot. We had some very hot nights in July, and for some fresh air, we had to open the windows wide. Then, due to the central location of the flat, some traffic noise was inevitable.
Our host was very friendly, helpful, always responsive, reliable, and had some very good recommendations. We recommend this flat.
