The studio is easy to reach from airport Tegel and close to a tram and S-Bahn stop - ideal to discover the city. It has everything you need and is spacious. Alan gave us more than enough information and maps about the neighborhood and the city in general! Would stay there again!
Only remark: Although I informed them that I will pick up the key at 20.00 I still had to confirm by phone an hour before. Leaving the key was no problem though.
