We were delighted with our accommodation - light, airy, spacious and immaculately clean. Access to the penthouse is via a lift, making it easy to get luggage up and down from street level. The apartment is located in a vibrant and happening part of the city - great restaurants and cafes, and very close to public transport. Dirk is a wonderful and welcoming host - and he makes a great cup of coffee.! We enjoyed our time in Berlin and would recommend staying at Dirk's apartment if you want to the true Berlin experience amongst the locals.
