There's a direct Metro to downtown which takes about 20 minutes and excellent bus connections as well. Vuosaari centre Columbus has its own post office, a City market (hypermarket), S-Market, a couple of restaurants, pizzeria, bakery, cafe, bookstore etc. The Health Centre and local library is next to Columbus - all within walking distance to Aurinkolahti. A newly built day-care centre.
Besides, a hop on the Metro takes you direct to Itäkeskus Mall just a 3-minute ride away.
Definitely a convenient and comfortable place. If someone can be so kind as to teach me how to insert photos here

Welcome to Finland and hope your move here will be smooth and easy!
