Guitar Strings For Blues Music

What’s the best place in London to learn how to play guitar?
I had acoustic guitar (nylon strings) and music lessons for three years at the age of 12 or 13 but never follow them through. I kept playing every now and then when I had the chance but never really made a habit of it because I felt I lacked a good solid knowledge that would provide some confidence and proficiency.
I’d like to attain this foundation knowledge so I can build upon it and try new styles. I’m particularly interested in Bossa Nova and other Brazilian styles. In the long run maybe go electric and try Blues and Jazz. I understand a solid knowledge of music goes a long way and wouldn’t be afraid to learn.
I’m looking for something very relaxed just as long as it poses itself as a genuine learning opportunity.
I’ve searched the web but either ended up with full-blown degrees or rather questionable offers by unknown individuals.
try the tube station.
