The apartment is spacious and very well located. It's nice having the two balconies, although the balcony on the cover photo is not part of the rented flat, since that's on the first floor. The price/value is right: the place is simple (certainly not "stylish", as mentioned in the title), but has all you need for a comfortable stay in one of the most interesting neighborhoods of Berlin. The cleaning could be better.
The part I didn't like, was the communication with Kai & Ulrike. I had to repeat my questions a few times to get an answer. And when I asked Kai for a nice place to have dinner for my 40th bday, the only answer I got was: "I do not live in Berlin but there are many nice restaurants around." There was also a bit of confusion about our late arrival, as the advertisement didn't mention untill what time the late arrival could be... but I saw they changed that now, so that is good, thanks for that Ulrike & Kai.
When we arrived, a neighbour was waiting for us outside the flat. She didn't introduce herself. She just opened the door and handed over the keys. No explanation about the flat, nor the neighborhood, and no house manual around either. One of the ideas behind Airbnb is "providing travelers with local expertise, flavor, secrets and knowledge"... Just don't expect anything of this when you decide to book this apartment, so you won't be dissapointed. But hey, for that price, you wouldn't, would you?
Nevertheless we had a very good time in the flat, I would recommend it.
