We enjoyed our stay at Serafin's place. He was extremely helpful and attentive, gave us advice on where to eat when we arrived and responded immediately to any question or issue. Alvaro enthusiastically checked us in and although we spoke no Spanish, he was able to explain everything. We loved the fancy coffee maker, and were supplied with coffee beans for our entire stay. It was a quick walk to the old town and other places in Bilbao and was a great base for taking day trips. It was also a very secure building. Thanks Serafin!
