We stayed in Ilves for two nights. The hotel is easy to find and in a good location. The hotel is also directly connected to Koskikeskus, which makes it easy to do some shopping.
Unfortunately, the first impression of the room was dirty. There was smudge on the table indicating that the tables are not wiped. Otherwise the room was tidy. On the second day we had to call the room service because the room was not attended to by 3pm.
The spa was great! One pool for swimming, one kiddie pool and a small space for sun bathing. It is not huge so it might get crowded during the holiday season.
Having been to other Sokos hotels, the breakfast here was disappointing. There was only one type of yoghurt, no granola, no pastry (e.g. croissants), small selection of fruits, no fish or nuts. The black sausage was a nice regional touch tough. These days I would also hope for vegan/vegetarian warm food options available for all.
