I stayed 3 months at Louisa's with a colleague for work related reason.
First thing first, the flat looks really like in the pictures. It is really modern, well furnished and cosy, and very clean. The location is close to the train station of Altstätten and you will find the all amenities you need nearby.
Louisa was a very considerate host, always ready to provide support and to make sure we were well settled in.
It was a real pleasure to stay at Louisa's and can warmly recommand her as a host. I would come back with pleasure!
