We stayed at Karsten place for four nights. Everyhting developed just the way se arranged it. Karsten was an amazing host, and was alaways on line when we needed to ask him anything. We founded the tram a bit noisy (although we were noticed) but a wonderfull experience to have.
The neighbouhood is wonderfull, really confortable a very well located. We will totally recommend Karsten place. The decoration of the apartment is superb!
