Raquel is really nice, she answered all of my questions and replied quickly.
The apartment is small but very well located next to the Metro Bilbao, but you can do anything by foot.
The apartment has the basic stuff, shower, fridge, bed, etc. but some of the equipment of the kitchen can be renew.
The only thing is that there is no elevator and for people with heavy luggage may be a thing, as it is on the fourth floor. There are building something in the apartment below so there’s a lot of dust sometimes.
