As we just arrived from a late flight, we got the keys from the airport R-Kiosk around midnight, which was very convenient. The apartment was next to the large Tripla mall, which still had some shops and food available after midnight. Parking was inside the mall. The apartment was nice, cozy and new, children loved the kids' room with colorful lights. It had a nice view and large balcony, more useful during summer. Host was very helpful and replied very fast.

Parking overnight in the mall is convenient and reasonable, but when keeping the car after the day starts, it might become a daily max 40 EUR pretty fast.

We really enjoyed staying in Cassa Onni. Apartment is quite big, very clean and with amazing view. Location is great,very close to train station. Our kids enyojed all the toys in the apartment. Taru let us check in earlier,which we really appreciated. I would only recommend this place when staying in Helsinki.

Nothing not to like

The balcony, the location, the spacy area, the well considered amenities.... I'd def come back!

I can't think of any!

Very nice balcony with great views! Good location! Private and quiet apartment, perfect for families with children.

Very nice, bright and spacious apartment with great views from the windows and balcony; very well located in one of the central public transport hubs of Helsinki - public transport, 24h groceries, etc. all nearby. A well curated selection of books comes as an extra bonus.
