I like libraries.
At least here in Europe. Wherever I've gone and chosen to visit a local library I was not dissapointed.
In Pula they have a huge kid's floor.
In Ljubljana all the smaller libraries are cozy and cater to kids . My faculty library's realing space is two relatively small rooms, both with a mezzanine. It's so private I would often go there for a power nap when I was experimenting with polyphasic sleep. The university's technical library has several huge reading halls where students can prepare to the exam. The atmosphere there is very conductive to work. I'd often go there to make sure I was making progress on my freelance projects.
In Sintra the library's floor layout is somewhat convoluted. It's built into a rock. There are many relatively small departments but all of them are present - complete with a music room, canteen and a full-blown garden with sculptures and playhouses for kids if you find your way to the roof!
In Maribor the main ilibrary is lackluster - it's situated in an 80's (i guess) shopping mall and is spread across two floors mixed with other businesses. But the University library! Oh my god it's so lovely. And lively! It occupies the western facade of the uni building. Even before you enter , chances are there will be some book event outside. And even when there's none, there's a livelyi "Owl" cafe (Sova), book return boxes and night reading room teeming with students outside the main entrance. So you don't even have to enter the library to feel the vibes.
