This is a very nice apartment with everything you need when you stay at Bilbao. It's very clean and neat, has great beds and a nice shower. Parking in the neighbourhood is free on sundays (our day of arrival) at the green lines. The next day we parked up hill, 15 minutes from the apartment. Valentin was very helpfull in explaining where we could park the car for free.
The place is very convenient to walk to old town and see the sites. Close to the tram and lots of shops and restaurants nearby. Valentin gave us good tips about where to eat (we liked the La Vina de San Fransico bar and the pintxos at Irrintzi were very good!).
The communication with Valentin was excellent. He is a very friendly guy who likes to help you with everything.
