Sonia is such a welcoming and kind host. There's nothing she won't do to help or make your stay more comfortable – she even offered to lend me her warm clothes when the weather took a turn for the colder! The room is spacious, the shower powerful, and everything was clean and neat. The flat itself is very quiet despite its central location – no more than 5 or 10 minutes from all the main spots, with lively bars just a street away. I wholeheartedly recommend Bilbao and a stay with Sonia!
