Daniel is offering his home. So this is not a renovated vacation unit but a place that’s home with all its little quirks, personal belongings, and even his cute outdoor kitty Geri showing up waiting to get some food each day. The beach is about 20min walking, supermarket 10, metro stop to Bilbao 10. We only used the car once to go to Gaztelugatxe (you need reservations to visit).
Beds were comfortable, area was quiet, there was an extra room as an office (had a bit of a musty smell - no problem in the summer with the windows always open), and the wifi worked very well over 20Mbps without dropping out. Parking was on the street and we got a spot in front of the building without problems.
Daniel is very nice and goes out of his way to make your stay comfortable.
