I'm a member of Internations Ljubljana (Slovenia), going for 2 weeks to Cartagena (24. 9. - 8. 10. 16). The reason is a short job exchange, but since I'll be alone in the city, I would really like, if someone has time for some mostly evening coffee/dinner/night out, etc. or short weekend trip in that period.
I also speak spanish, german, croat/serbian, some portuguese beside english and slovene, so, expats in Cartagena, looking forward to meeting you ;-)
