Nice accommodation, right in the Casco Viejo (Old Town) which is a very good starting point to explore the city. The room we were in was not too big, but it was tidy and the everyday cleaning service was great. The noise from the streets is substantial and it could present a problem for light-sleepers although the host provides ear plugs. Also, we were lucky it wasn't too hot in Bilbao during the days we were there because it was quite warm in the room. There was an electrical heater/cooler in the room, but I'm not sure it would help much during heat waves. We couldn't connect to the Wi-Fi, although we admit we didn't report this problem to our host during our stay. The check-in/check out process - super easy. We didn't have breakfast during our stay, so I can't say anything about the quality or quantity. All in all - 7Kale B&B is a good place to stay while you're in Bilbao, just be mindful that you are right in the Old Town where the street noise is a normal everyday "addition".
