This was my second stay at Cristina and Alexander's flat. It's a terrific location, overlooking the piazza at Hackescher Markt and literally a stone's throw from the S-Bahn station (plus trams right next to the S-Bahn and the 100/200/TXL buses within a couple of blocks). Within the same block are conveniences such as a Spätmarkt and ATM, nearby there is a Bio-Laden and regular grocery, bakeries and cafes, a twice-weekly open-air market, and loads of places to eat even late at night. And of course with the access to transit it's easy to quickly get around the city--only two stops on the S-Bahn to the Hauptbahnhof. It's a comfortable, clean, bright, and spacious apartment, equipped with everything I needed. Nice kitchen, good wifi, comfortable beds. As I'd mentioned in a previous review, the bedrooms are in the back of the apartment and very quiet at night. Cristina and Alexander are responsive hosts and the whole stay was once again a very pleasant experience. I'm hoping to be back!
