Absolutely wonderful hostel. Big breakfasts. Nice little pool (pretty chilly in October though). Ping pong table. Well-equipped kitchen. Hot showers.
I stayed in three of the dorms in my time here, and all were comfortable. The four-person named Madera (all the rooms have different colours for names) probably offered the best night's sleep.
Single best thing about Coloria is the staff – all friendly and capable. Only one lady who doesn't speak English, but she did her best to teach me Castellano.
Super close to the main square of town, plus only 15 minutes from Balcarce, the nightlife area. A corner store one block away has basic cooking stuff, and there is a big, European-style supermarket with a carniceria only 5 blocks away too. Go left out of the hostel three blocks until you hit Avenida Mitre, then turn right and walk 2/3 more blocks.More
