The morning staff was extremely helpful, while the evening staff was always a lot of fun! Beautiful rooms with views out over the Avenida de Mayo, though the beds were a bit hard. I had a large locker, but some people were stuck with half-size lockers that definitely wouldn't have fit everything. Very cool roof terrace and very social atmosphere!
A bit of a hike up the hill to reach this hostel, but a lovely oasis once you get there! Nice dining room area for hanging out, though the kitchen area for guests is tiny. Great group of people was staying there, so that really made the trip!
Had a fantastic time at Uvaia - wonderful staff, met some great fellow travelers here. Good common room and bar area for socializing, good size fully-stocked kitchen. Each bed has a light and power outlet, making keeping your things charged very easy. Big lockers beneath bed with enough room for large backpack and small roller bag with plenty of room left over.
