Great and stylish apartment. Very clean. Communication with a host was excellent. We had a late check in and he was kindly waiting for us. A street at night can be a bit tricky at that part of neighborhood and I would not recommend to walk there alone. But during the day its absolutely safe and ok.
Our host helped us to call a taxi to the airport in the morning, because we don't speak Spanish. We enjoyed our stay in Bilbao!
