Staying on carrer de trafalgar was brilliant, I wanted to be pretty central so I could get everywhere on foot and just roam around + get some work done and the apartment was perfect for both. There are some amazing restaurants 20 mins in any direction.
In particular I recommend this one: https://casalolea.com/
I would like to come back at some point hopefully in the near future.
Thank you very much Andrei and Alina!
