I really liked Apple Hostels and would stay there again. There's a few minor "quirks" like with most hostels. For instance, they hand you your sheets/pillowcase/towel to take to your room and put on yourself, maybe this is for cost savings, but it's a bit odd.
Otherwise the room was great/clean. We wanted it a bit cooler and a simple request at the front desk took care of it. The main room to hangout is very nice and well used.
We arrived late at night and the walk through the alleyway to get to the entrance was a little interesting. Probably would recommend going around the block to the east and entering the alleyway from the south.
Would stay again though, for sure. All issues were minor at best and we enjoyed our stay.
