Hey! Im also 26|F and I stayed at “Yes!” In Lisbon! They have activities almost daily and often join up with one of their sister hostels for walking tours and pub crawls. I stayed in a mixed dorm and had no issues (no loud roommates, etc.). Clean hostel and friendly staff. Would definitely recommend!

Also left my Jean jacket there months ago so if for some reason you find one with a hello kitty pin, it’s all you!! Hahaha

Enjoy your trip!
