The Art department of Akateeminen kirjakauppa (Academic Bookshop) is an infinite source of inspiration. Since the store is located right in the centre of Helsinki it is easy to just drop in. The Store is designed by famous Finnish architect Alvar Aalto so even if you’re not into books it’s worth visiting.
Tramline 3B will take you almost anywhere in downtown Helsinki. If you want to get an overall picture of the city centre and its surroundings taking a tour on this tramline is a good way to do so. 3B is the only tramline that operates late at night so if you’re visiting Helsinki there’s a great chance that you’ll end up using it.
Töölönlahti Bay is a really nice area in the middle of Helsinki. It's a lovely walk around the bay and especially in the summer you can sit down and have break at the café located up on the hill and enjoy the view.
Kipsari is a vegetarian restaurant/bar in the premises of Aalto University School of Arts, Design and Architecture. I enjoy its cozy atmosphere, the beat-up sofas and dim lights. There’s also a small gallery for the students. Kipsari is run by ARTS student association TOKYO ry.
