The apartment is in an old building, it actually has an elevator, which is tiny but its there after all. The check-in was fine however when we checked in it was not very clean and it smelled like mariuana. To be fair its not super dirty but you see stains of glasses on tables, and there might be hair you find at some places.
The apartment looks used, not like trash but used and a lot of stuff could need renewing, since even the curtains had wallpaint on them. You need to get up a bit earlier than other people in the building to shower since elsewise you will have no water coming out the shower, to be fair, thats normal in old houses and not really an issue. Its also kinda cold in the apartment because it probably does not have a heater like most buildings in spain.
It is quiet central and nor far from the metro nor the airplane bus.
I think it‘s fine if you have few options but i personally would not book it again. Additionally i find it awful to ask for tourism tax after you paid the price. Airbnb actually says that this is the final price, however i was not wanting to look for another apartment a week or two before we got there, so keep in mind that you gotta pay like 30€ for three people and three nights
