I was in April’22 for 2 nights. The most profitable option is not far from the airport and the center. Everything is close in Lappeenranta. The hotel is modern, although the building is historical, inside it is chic modern. The room is cozy at home, there is a recreation room with a kitchen. Breakfast is modest, but you can eat enough.
A lovely hotel in the old barracks building. A simple interior. Comfortably. Play room. The breakfast is modest, but good. There is Parking for guests (which is not a little important - free).
