We didn't really know what to expect when booking this place, but we were very pleased with our choice. Each room has it's own separate bathroom using your room key. There is a safe in the room for your valuables. The room was very spacious for two people, almost the size of a small apartment. If you are a light sleeper request a room facing the courtyard and not the street since the sound of traffic can be a little noisy. The staff were extremely nice and helpful. There is someone at reception 24 hours. Breakfast was really good, much better than we expected with fruits and other healthier options (aside from the usual biscuits and croissants). Mendoza was very inexpensive compared to Chile for both accommodation and eating out so all in all a very good value if you're on a budget. The neighborhood is safe and has lots of shops, restaurants, cafes, etc. The only thing that was a little questionable was leaving our keys at reception with one staff member and just giving our room number (no identification) to get the key when we returned with a new staff member at reception. I'm not sure if this is the most secure process to have in place, but maybe I'm just a little paranoid or maybe they are really good at remembering faces. Anyway, we made sure to lock our valuables in the safe whenever we left... just in case. The rooftop patio was out of this world with all the cacti and other plants. Highly recommend Hostel Confluencia.
