Great communication. Apartment is out of city centre a bit but this was nice for us. There are lots of nice bars/restaurants and shops very close by. It is very easy to get around and the number 26 bus is just outside and will take you to the centre/beach in 15 minutes. It is also a nice 30 minute walk either and the metro/train is also available although this wont take you to the beach. We preferred zurriola beach - less busy and great waves. If you take the metro one stop in the other direction it will take you to a lovely public outdoor pool with sunloungers etc for just 6 euro.
Having no air conditioning was a challenge in 40 degree heatwave but Manu went out and bought us a fan which was nice.
Manu also gave us a recommendation for bar del lobo - you will need to book and there are a number of nice bars and restaurants in that area which are a nice change from the old town area.
All in all great stay and city. The apartment was spotless, neighbours were friendly and the area is well serviced with everything you need.
