Check In: Was done with Roberto's dad who was at the apartment when we arrived. He was a gentle and kind man who made sure he explained everything to us and gave us a few suggestions of the area before he left.
Communication: Was good and prompt. Roberto was always available via the airbnb platform.
Cleanliness: Roberto's place was clean.
Accuracy: Everything was as described and as shown in the pictures. However do be aware of the low wooden cross beams in the apartment. I am pretty short at 5ft 7 but I accidentally hit my hand on the beam one day when I was just taking off my shirt.
Amenities: Everything which is listed was available and in working condition.
Check Out: Roberto allowed us late check out and also gave us the option to leave our luggage at his place which is a 15 minute walk away from the apartment as we had a late flight out of Bilbao. Very much appreciated.
Location: We did not check out the neighborhood and the apartment is located one street away from the river. The street itself has some interesting characters but we never felt unsafe. However I will have to note that if Google Maps ask you to walk through the San Francisco area which is the adjacent neighborhood for a short cut into the city, I suggest taking the longer route and walking along the river. We walked back one night from the city and we did not felt very safe. I am not sure if the presence of police every 10 steps helped along the way.
