This is definitely the place to stay in barcelona (if it's available).
We work remotely so wifi, space to take video calls, and privacy are key factors for us.
This place has great wifi-- we had multiple people on multiple devices taking video calls without an issue.
The place is massive-- we had ample room to take calls simultaneously without bothering someone else.
Privacy-- you're near the top floor of the building with polite neighbors and an incredible view.
Can't beat Marco's place and his great communication. Highly recommended!
