The apartment was great, nicely decorated with high ceiling, clean with everything you’d need. Location is pretty central, easy access to shops restaurant and to museum island. Everything is in walking distance.
Karsten is a real super host, he is really nice and helpful in everything you’d need. Once I had forgotten my keys inside the apartment, I gave him a call, it took him literally 12 mins, to come over and open the door for me.
So if you happen to find this apartment free, I definitely recommend you taking it.
