Jakob's flat is tastily furnished and comfortably equipped. We felt very well there. The location is very attractive, there are many cozy bars and restaurants nearby.
We had no contact with Jakob. His flat is managed by Cheryl, who also does this for many other apartments.
Which leads me to the only point of criticism. Checkout time is very inflexible. Although there was no follow-up booking, we had to leave the flat at 10 am, so we couldn't fully enjoy our last day. Later checkouts were never a problem in our previous stays.
