I've stayed here on two separate occasions and during both visits, every staff member I came into contact with polite, courteous and professional, and in a few cases, demonstrably eager to be accommodating. Such good customer service makes me comfortable to say here again.
But although this hotel is very competitive on pricing when it comes to their cheapest rooms, those rooms don't have air conditioning, which often isn't needed in Medellin, though sometimes using aircon enhances comfort on the hotter days. And at this hotel, you have to pay a few dollars more to get it (roughly $4-6), which I did y 2nd stay, and when you do that, some other hotels become very competitive to this one, with newer rooms and a few more features, eg desk and chair.
So at the price point for the aircon rooms, I'm certainly willing to stay at Central Plaza again especially considering the excellent customer service and overall good value, but I'm looking elsewhere on my upcoming trip to see what else is available that I might like more.
