Anna's apartment is huge - easily big enough for half a dozen people to stay in - and excellent value at the listed price. It's only a five minute walk to the nearest U-bahn stop, and not much more than that to Friedrichstr. and the Brandenburger Tor. The apartment is well-decorated and furnished, clean, tidy, on a nice quiet street, and would be perfect for a longer trip. The only downside is that breakfast isn't provided, but this is stated in the ad, and it was our fault that we didn't read it properly. Overall, I'd definitely recommend it.
