We stayed at Mar's place for 5days in beginning of August. We never got to meet Mar in person since she was on vacation. But her lovely brother greeted us and gave us some good tips of the city :) And if we hade any questions Mar was just a phone call away!
It was a really high standard, modern and cosy apartment/studio perfect for a couple on holidays :) the location is good, it's fairly close to just about all in BCN.
In all we really loved the place and would absolutely recommend it to others!
Best wishes
Christian and Yulien :)
