We spent an amazing time in Gerhard and Nicole’s flat ! It’s a very nice and clean loft, and we immediately felt good in it. The situation is perfect as it’s not in Innere Stadt but very close (10 minutes walking or less by public transport), and there are many restaurants and places to go out around but the flat is still very quiet. Communication with Gerhard and Nicole was easy and they were reactive and welcoming. I warmly recommend !
