Single room for rent - 9014 St. Gallen, Haggenhaldenstrasse

Looking for a roommate in the row house. Since it will be a 2-person shared apartment, it is very important to me that it fits personally.

I am 28 years old, sporty and very active. Being alone, the house is now too big for me (145m2).

The house has 3 floors: ground floor, upper floor, and basement.
Basement: laundry room, a room converted into living space, currently set up as a cinema room, as well as a cellar compartment.
Ground floor: WC, kitchen, living room, front garden, and garden.
Upper floor: 3 rooms, as well as a bathroom.
Additionally, there is the attic with virtually unlimited storage space (accessible via a ladder).

2 minutes to Haggen train station.
By public transport:
4 minutes to St. Gallen
5 minutes to Herisau
