The apartment is well located and offers everything you need - there was even an iron that was an unexpected bonus. The proximity to U6 is a real advantage. The Bergmann Kiez is a great place to experience Berlin.
The communication and check-in were easy and well explained - no problems and very fast responses to questions.
The sheets and towels were professionally cleaned and were of good quality.
Where it needs to improve is in overall street noise proofing and general cleaning, but I am sure that will be looked after.
If you use your key to fully lock the door, the lugs engage and it seals better.
