I stayed for a little over a month and it was great for a long term stay.
No issues with communication.
Has all the appliances you should need.
The location is nice not only because it’s off of las Ramblas and a nice walk to the beach and other areas, but it’s right next to the Liceu metro station.
I work remotely inside the apartment and it has a nice balcony which is important for me to take breaks from working.
Something helpful that I didn’t figure out until near the end of my stay is that there is an HDMI cord in the drawer of the stand which the TV sits on. Can hook the TV up to your laptop if it has an HDMI port to watch movies or whatever from your laptop (because the TV is not a smart TV).
