It was our first time to rent an apartment in Berlin. We've booked a hotel (the same each time) since 2007.
Now we will only rent apartment from Alex: it's close to everything - KaDeWe, gay area, S-Bahn/U-Bahn, shops, restaurants etc., it's clean, it's spacious, it's quiet.
Actually, we didn't meet Alex but we met his friend Michael. He is very-very-very kind and nice and he feels like your old friend :)

It was a great pleasure to stay there.
