We (family of 4 incl. 2 teenagers) stayed for just one night in August. The apartment is very nice and just like in the photos, but it is not a loft, it is a basement flat (so there are no views as one might expect from a loft apartment). Everything was very clean, the beds and sofa bed were very comfortably and Julen was very friendly and helpful, giving us tips as to where to park in Bilbao, and there were also information brochures in the flat. Parking is easy and free. The bathroom and shower are spacious and the kitchen is well equipped (coffee maker, kettle, microwave etc.) - except some basic kitchen implements like sharp knives, tin opener, spatula etc., so if you plan on staying longer and cooking your own meals, you might want to bring your own. Otherwise, I can highly recommend this flat.
