Guillaume's place is great for remote working as the internet connection was superb! 5G wifi hotspot allowed me to work without issue, and the modern layout of the apartment allowed me to feel as if I had a home office to myself. The kitchen and bathroom, as well as washer/dryer were all modern and clean. I was able to live as if I were in my own home while still having access to all Barcelona has to offer! Definitely recommend for business travelers to Barcelona.
