Had a great stay here. Some may say it's a little small but it's a perfect size for what we needed. A little outside of the centre next to a lovely canal, it's really close to two rail station offering you options for different lines, and with trains so frequent it's easy to access all of Berlin.
Communication was great, even when we were there and had a question about the apartment.
We had an early flight and were allowed to collect keys early as no one was staying there the same day. Could not have been anymore accommodating. Gunter also arranged for a iron and ironing board to be waiting for us after we enquired, which wasn't on the itinerary.
Would highly recommend a stay here if you're looking for somewhere well priced in a great location
