The location is fantastic near everything, including a small supermarket on the other side of the river (5 mins). The studio is exactly as described with an excellent sized bathroom. Reza had some coffee, tea, milk & some bits to start us off, very helpful as we arrived at midnight. The bar downstairs is excellent, busy with a great atmosphere.
The only thing to be aware of is that the hot water tank is quite small, as long as you are aware of this it is no problem. The wifi is excellent.
I highly recommend this studio & we will definitely stay there again when next in Bilbao!
