I'd like to share a different view on Medellín. Most of the stuff that is written here is really positive, although it is acknowledged that in Bogota for example there are more things to do.
Anyway, I've been studying here now for quite a while and I am actually getting bored with the place. Coming from Western culture, there are some nice things you start missing here. Of course it's up to each individual what kind of lifestyle you live and what things you appreciate. For me, it's just not enough that city is full of silicon boobs if other things are lacking. Don't get me totally wronge here: I still think Medellín is a nice place to visit and I dont actually regret being here, but I just want to give another viewpoint to people on this great forum who might be thinking about spending more time here.
What's Medellín missing? Here are some things in random order:
Good, quick, somewhat healthy food, like real bread with some stuffings. Sorry, mr, no can do. Only pasteles and overly greasy empanadas available. Food culture in general is pretty sad, as every place has usually the same basic lunch. Of course you find more stuff in Parque Lleras area, but the prices goes up there as well. What about wine? that's available of course, but prices are really high, so there's not really wine culture here. Cultural offerings, like theatre, international bands doing gigs, jazz clubs, electronic music parties with something else than minimal house, nice cafeterias.. Cant find much of them. What there is, though, is crazy amount of generic looking bars with reggaeton, crossover and lots of local music (salsa, merengue etc..). The traffic is also horrible, and speaking about traffic and overall logistics: it's really hard to find a good place to jog in the city, there are not really nice parks, logistics are horrible for pedestrians. And in general, the city is just quite butt ugly. I mean the main square with the important buildings is like a joke.
My spanish is ~intermediate level, so I guess if it was totally fluent, I'd be getting more out of the city: could tap into local cultural offerings better, get more local friends etc. Well, I don't want to sound too obnoxious, but in general the local guys that I've met here are not so interesting. Not many have travelled or really have interesting lifestyles (hate to define ppl like this, but it holds true). I mean, if it's your thing to go and drink aguardiente in Parque lleras every weekend and talk shit, i guess these ppl can be super interesting then. And of course it's always about the social circles. The top ones have not really been available for me, more like middle class ppl that I've got to know. Ironically, I've met many interesting gringos, and many of them actually share the same experience..
I want to point out again that of course the good things are there: the weather, the girls, the drugs (after seen so many gringos coming for these, there's no point denying that this is really one of the attractions here) and so on, but if you want to invest in real estate here for example, or live here for longer, think about all the different things you want to do and what your lifestyle consists. Don't get too much fooled by the silicons
