I absolutely loved my stay at the GHL!
One small BUT highly differentiating factor, game changer in my opinion, I did not fully appreciate until now is the sound proof window I got. (I visited two other hotels in Colombia and they did NOT have the sound proof windows. It can be extremely tough/ impossible to sleep, when music plus street noise is constant, especially true in the El Poblado area of Medellin.)
It checks the box for nearly everything. It is somewhat outside of the core, which means you’d need to take a taxi or walk. I didn’t mind it much because it checked the boxes for everything else I was looking for, e.g. cleanliness, top notch service, and amazing views of the castle. I’d go back to GHL for sure.
