Carl's apartment in Kollwitzplatz is one of the best places we have ever stayed in on Airbnb - stylish, comfortable, spacious, great value, brilliantly located, and with a host who really cares about your comfort. The bed is huge and comfy, the linen great, the kitchen and bathroom superb, and the deck and access to garden wonderful even in cold weather. In now very-chic Prenslauer Berg, it's surrounded by great restaurants, many of which are good value, and is 5 minutes walk to the tram to Alexplatz or the U2 ubahn at Senefelderplatz. There is a grocery store literally next door, and loads of other food shops, bakeries, etc, in the vicinity. Try be there too, on a Saturday, so you can experience the wonderful street market. All in all a wonderful stay - this is Airbnb as it's meant to be!
