Great place! Looks exactly like the pictures and Mariola was an excellent host. It is located in a very quiet building and oberlooks a small inner courtyard so is quiet at night also. Apartment is located about 3 mins walk from Bilbao metro station and plenty of grocery shops bars pharmacies and places to eat really nearby and about 20 mins walk to gran via and the centre of the city. Air conditioning works great and is definitely needed in the height of summer! One very minor downside is that there are no doors in the apartment so it might be a bit noisy if more than 2 guests. Had a minor issue with the door being bolted on us one day which meant we were locked out for a bit but Mariola was quick to reply and sort the problem. She was also very accommodating for check in and check out!
