I had a very positive experience overall. From my initial contact to my departure everything went smoothly with my contact with Patrick. My flight arrived into Berlin fairly late but he was most understanding. On my day of departure, my flight was late in the evening & again he was understanding and I was able to leave later in the day.
The spacious, minimalist & clean room worked well for me during my stay of 1 week. Importantly I experienced the place to be quiet & peaceful at night ensuring a good nights sleep.
Re location it was only a short, leisurely 10/15 min walk to either Warschauer Straße Station / trams or Ostkreuz Station. Both have several connections to other parts of the city.
And finally, I would return again & stay at the same place & I would have no difficulty in recommending a stay there to other people. Thank You Patrick & best wishes for the future !!
