Positive things - Great location near by s Bahn and u bahn grocery and all other requirement Nice flat with necessary amenities
Perfact check inn constant responseand helpful host, good tips
Nagative-You have to climb five floor and no lift so if you are coming with lots of luggage or knee problem than it might be problem
Inside house in room there is no lock so if you are in group with two couples or young children it might be problem for your privacy but i expect sebastian will act soon on this issue and he is very positive and understanding and helpful.
Else i recommand and give five star .
