Elena is a very friendly and nice girl!
We had some communication problems but we also solved it (I wrote her a message when we will arrive in the morning but maybe she didn´t get it and she also speaks not english!)
but it was not a big problem, but 1 hour later her mother comes to the flat nad opend us the door.
She and her mother helped us a lot!
They are very friendly people, they gave us information for the city, so both of them are very friendly and helpful persons.
The flat was also clean, there were towels inside, enough space, a nice balkony, so it´s a very nice flat!
If will go again to Bilbao I will book it again.
