The apartment is a nice size for two people sharing with an ample bedroom/living area and separate kitchen and bathroom, all tastefully furnished. It is set back far off the street and overlooks the back of the building so is lovely and quiet. My only complaint would be that one of the windows in the bedroom doesn't have a blind so we were woken up by the light.
The area is great - lots of places to shop, eat and drink in the immediate area and a nice stroll into town. It's also only a few minutes from the U-bahn which is ridiculously easy to navigate. All in all a great place to stay when visiting this brilliant city!
