I stayed at ukonlinna for 3 nights intentionally but only stayed for 2 in the end because I soon realized I was going to be on my own with no staff or guests on my last night! I wasn't aware of this until I asked the question. The staff leave at 8pm every night. Although staff were very friendly and welcoming I had a very pleasant time there. However I was disappointed I was not notified and found myself paying for another hotel room at 9pm that night as I did not feel comfortable in the hostel alone! Buses are not frequent into Imatra from the hostel, I was kindly given a lift to the shop for my food by staff on my arrival which I am grateful for!
Nice and clean, rooms tiny, plenty of space in the surrounding areas of the hostel which compensates this. More
