I reserved the 2 double beds with the 3rd bed option for my stay. The room had a "courtyard view" (i.e., overlooking the mall); it was quiet, spacious, spotless, had a nice sitting area, and the bathroom featured a deep soaking tub. Other room amenities included a mini fridge, coffee maker, safe, iron & board, desk, and generous clothing storage. I was not given a bathrobe or slippers - perhaps my room wasn't of that class? I didn't ask for them, either, as it simply wasn't that important to me, but YMMV.
The breakfast was a bit chaotic during the weekend, but that isn't unusual. There were many options for vegetarian/vegan and gluten-free, as well as the usual fare.
The sauna was delightful. If the opening hours were extended (earlier, later, or both) and morning hours were available for weekdays, I'd have used it more than I did.
The hotel itself was very nice, looked well-maintained, and was clean. The staff were wonderful from check-in to check-out, and I appreciate that they extended my checkout time without fuss when I inquired, especially given that my request was last-minute. Proximity to Helsingin päärautatieasema was important as well.
I didn't eat at Restaurant 10. Kerros, but Casa Largo was wonderful. Hesburger was wonderful as always; S-Market was a huge bonus, as was their huge assortment of Long Drink.
Overall, my stay was excellent, and I would stay here again in the future. Kiitos!
