Joseba's appartment is in a very convenient location. The bus stop to and from the airport is a hop and skip away; important sites are all walking distance too; a supermarket is just next door. The flat is spacious, very clean and well maintained. As for the room itself, there is plenty of space and light, and the little arm charm is great for chilling in after a long day of exploring.
Joseba was an awesome host - super friendly warm and accomodating. He let me check out later as my flight wasnt till the evening. If he has time, he usually organises a tapas night with the other guests, as he did on my last night. It was an fun and great way to meet other travellers.
I highly recommend Joseba's place during your stay in Bilbao!
