This is a great little flat just on the edge of old east Berlin, only short walk from the tram (U-Bahn) and then a couple of stops (5 minutes) from the heart of Berlin. It's one of those, up and coming areas, with a high quality supermarket a couple of blocks away and some good restaurants within walking distance too. I don't think it will be long before this area is a hive of activity but for now it's nice a quite.
The flat itself is in a quiet residential block on the first floor, and all the fittings are brand new and work as you would expect. I have stayed in 4 star hotels with lesser bathrooms and this even has a washing machine.
All in all a great place to stay and I can't wait until I go back to Berlin, as this will be first place I try to book.
