Great appartement ! Very spacious and luminous. There's everything you need in the kitchen and the coffee offered by the host was much appreciated. The 2 bathrooms + 1 toilet are really handy for a big group. And the location is great: so close from the old town where you can go by taking the beautiful Mallone Galtzada. But in a (not so beautiful it's true) really quiet area, and that's very precious because it offered us the best sleep quality in our north of Spain trip. And the parking spot is useful too.
The weather was not so nice when we stayed in Bilbao so we didn't had the opportunity to try the swimming pool, that is located in the shade of the house.
If you're hesitating, just go for it! Welcome and comfort were the best we had on our trip.
