I play at 6.5 Playtomic and I have spent three years coaching friends. If you are serious about improving, I will give you the best 90-minute session you have had abroad. Technique drills, then competitive doubles. I want 4.5+ players only.
Quick coffee at Nomad Coffee Lab in Poblenou -- best espresso in Barcelona. Then you go play or I give you 15 minutes of video analysis on my phone if you want.
