I'm thinking about moving down to Manizales this winter for a few months. I stayed in Medellin for awhile and loved it. Looking to study Spanish a bit more (already fluent but terrible grammar), take classes - perhaps drawing/painting, art history, who knows? I'm an ER doc and I'd be happy to volunteer as well.
I saw your suggestions for renting an apartment long-term. Do they have good short-term furnished rentals for that time period? Is Manizales bike-friendly? I'd like to bike around but might buy/rent a scooter. I'll want a nice gym as well.
Also would definitely like to engage the expat community. I've been a Couchsurfer for years and may be willing to take hosts when I have an apartment.
