I really enjoyed my stay in this apartment and would recommend it to anyone visiting Berlin. You should know, however, that Vladimir seems to have several apartments available through AirBnB, and you may not know which apartment you will actually get until close to your arrival; the one I got was not actually at the address listed when I first made the reservation. I did not find out where I would be staying from Vladimir until two days before my arrival. So my comments really relate to the apartment on Wallstrasse that I stayed in for a week, I can't comment on the other apartments, though I'd guess that they are similar and equally good. This quite modern apartment was very clean and well equipped and got lots of light; having a balcony was particularly nice and I spent a lot of time on it having coffee, reading, etc. in the lovely Berlin summer weather. Having a separate bedroom was nice as well. Perhaps most importantly, the location is excellent: everything in Mitte (including the "Museum Island," Alexanderplatz, Unter den Linden, etc.) is in walking distance, as is Kreuzberg, etc.; but there is also a U-Bahn station (Spittelmarkt) just a few minutes away, and there is good bus access too. Wallstrasse is a relatively quiet street, with some nice shops, cafes, restaurants, etc. nearby -- though a larger grocery store is a bit further off. Vladimir was easy to contact and responsive; the only issue with the apartment when I arrived -- the glass carafe in the coffeemaker was broken and needed replacement -- was addressed promptly. The wifi was generally good, adequate for streaming video, but it not infrequently cut out for a few minutes at a time; this problem should be resolved (though perhaps it's a building-wide problem?), so that internet access is steady and reliable (and maybe a bit faster?). Overall, I'm quite happy that I stayed in this apartment, which served me very well, and I had a lovely week in Berlin.
