When my friends and I decided to visit Costa Brava, we were looking for a home and that's how we found Sara's apartment on Airbnb. I'm going to the list out the good, bad and ugly:
Good: Location was semi decent as the beach was still a car ride away. The host had arranged key pickup and the lady who delivered the key was lovely. The neighborhood was quiet and while the apartment had an upper floor we never heard any noise. The kitchen came well equipped.
Bad: The lane on which the apartment resides is very steep and parking was an issue. The bedrooms were in the basement and well while we knew that, the second bedroom literally was a hole carved in the wall wth a bunk bed.
Ugly: The basement had a very foul smell of sewage and it was horrible down there. The toilet was filthy specially the bathing area.

Very disappointed. Could have lived with everything except the sewage smell in the bedrooms and toilet.
