Staying in Steffi's apartment was great!
The only thing i missed is staying much longer!
The place looks exactly like from the pictures, perfect for 1-2 people. Has everything you need to feel like at home and is very new and clean. The location is TOP. I could walk everywhere and for the 5 days stay used metro once.
I would warmly recommend it, and I hope I'll have a chance of staying with Steffi again.
