This is a fantastic flat. The description says cosy so we were expecting it to be quite small but it's very spacious and airy. The decoration is lovely and very tasteful, it was spotlessly clean, the flat is very quiet and although it's not bang in the centre, it's only a short walk to the Casco Viejo and other places of interest in the city. There is also a car park nearby, which is very convenient. The flat is fully equipped for anything you might need for a trip to Bilbao, with thoughtful touches like a metro card for guests to use for their stay.
We would definitely stay again if we return to Bilbao and would highly recommend it to others considering places to stay in the city. Thank you Iker!
