Arinas apartment was perfect! It's located right above Plaza Catalunya (which is the center of Barcelona), and looks amazing exactly like in the pictures!
Arina herself was very responsive and helped us with everything we needed.
Large enough for 8 people easily, the apartment has everything you can ask for, including washing machine and a dryer!!
If you think about planning your trip to Barcelona, you should definitely contact Arina and try and book her flat.
