Very nice apartment in Sestao, there is enough beds to fit 4 people in if you count the couch and you will find all the basic equipments you need for your stay.
A bit hot in the summer as there isn't any air conditioning but the very wide windows will let the wind through for the night.
However, the train passes just in front of the windows, that did not keep us from sleeping with the windows open but I thought some should know as it can bother people.
Very easy to get in and out of the apartment. Rebeca replied in time for everything. Communicating was a little difficult for us sometimes as she doesn't speak english contrary to what's written on her presentation, just use G. Translate 😉
I will definitely come back when I'm visiting this area again !
Thank you again Rebeca
