It's a great apartment: perfectly situated, very clean and spacious.
The room itself is perfectly equipped including a very comfortable bed.
Taken as a whole it's just a great apartment.
However, what makes this apartment not just great but absolutely awesome is Emir. He is one of the coolest hosts I've ever met. He doesn't spend that much time in Berlin but if you're lucky enough to meet him you're going to have an amazing time.
I absolutely recommend this place, its beautifully located and Emir is just the nicest host you could imagine.
