The place is great, good location from airport with airport-bus then streetcar to Ribera and 2 min walk.
Walkable distance to shops, Guggenheim, promenade and all things you can visit.
Neat to bars, restaurants and a supermarket. It brings a lot of noice but as soon as you sleep it does not matter.
The apartment is very clean and has all you will need even coffee-machine with cups, oil, milk. You can cook but all the restaurants and Pintxos places downstairs are so good that it is. A waste of time.
Mind the 70 steps up, we have loved it and Santiago helped us with the suitcase - we are grateful for this.
Check-in and out are easy and pleasant. Santiago is a great host and has some nice amenities when you forget them from home.
We will book it again and miss Bilbao very much!
