If you hesitate between this appartement and another. Well this one is definitely a very good one. I'll start with the cons and finish with the pros as most of the time we remember with the end so don't skip.
The only cons for us (we where 4 ) was that the house is situated near a traffic zone so I was a bit afraid at the first approach but when Lidice let us enter the house we entered in a very comfy appartement with a very good noise isolation from outside so we felt like home. There where some attention to us, all the rooms are clean bathrooms are very nice. Well it was perfect to us it is easy to park so definitely a good choice and I will choose this one again if I come back to Bilbao for sure.
