Merta (which means crayfish trap in Finnish) was finished in 2013. It has 18 rooms and a small apartment for long-term stays. Each room has a bathroom, TV and terrace/balcony.
Ten rooms have twin beds (90 cm), eight rooms a double bed (140 cm).
Four rooms also have armchairs that open up as beds.
The decoration of the rooms drew its inspiration from the surrounding nature.
