You're never too 'old' for youth hostels
There were people in their 60's staying in the hostels so you are fine.
I recommend checking out K's House hostel (always recommend them on the forum) as they provide cheap and good quality hostels with friendly staff.
I was thinking for a while, does the youth hostels just supports to sleep the night? Does it has anything else except bed? I mean like a toilet or a bath? And another question, does it a share room? Or I'm the only one who is going to sleep there?
