I stayed 10 days in the apartment, partly working remotely and partly exploring the city and it is perfectly suited for both! The apartment is everything you're looking for and just as described and shown in the photos. Very spatious, very clean and included everything necessary. The communication before and the check-in/out was very friendly and also the offered in-between services were great.
The location is perfect: lots of restaurant and bars just around the corner, a big supermarket right across the street in case you want to cook yourself and pretty much everything in Barcelona is reachable within walking distance.
I can highly recommend the place and will for sure come back.
