Max's apartment is fabulous, it's spacious, airy and stylish. The location is great too, the street has plenty of amenities, I.e. bars, restaurants and shops/supermarket, and was surprisingly quiet. It'quick easy to get into the city on the Ubahn, we also decided to walk one day, which took about 40 minutes.
Just a tip for anyone heading there soon,there is engineering work on the northbound Birkenstraße Ubahn platform so if you're travelling north on the U9 line you'll need to get off at Westhafen then the tube back the other way or walk (5 mins).
The only thing I would have improved about the stay is the mattress on the double bed, I'm not normally particularly fussy about the firmness of a mattress, but this one was way too soft for me.
