Love love loved this spot!! The location was a tiny hard to find (and we were driving which made the street navigation a little crazy) but once we were checked in it was the perfect spot as our home base while in Bilbao. I only wished we had stayed longer!
Sonja met us personally and checked us in. There was coffee for us to brew and delicious fresh bread for us to eat in the morning.
Parking in Bilbao is very difficult by the way, just in case you are planning to drive. We ended up parking across the river in paid parking spots (about 15€ per day) but if you feel like driving around for hours you may find free spots.
Overall- a wonderful experience!
