Wow! What a super host, Cos was amazing and went over and above what I would expect- in the late hour he printed off our Berlin Welcome Card and brought it over- 10/10 for that - this was so appreciated.
Our flight got us in before our check in time, but Cos still came and met us at the apartment and there was no issue with it at all. We left our cases and went to explore around the area until the apartment was ready.
The apartment itself was really cool - really modern and tastefully decorated. Everything you needed in the apartment was available and the location of the apartment was great. 2 subway stations nearby.
I would definitely recommend this apartment to anyone wanting to stay in Berlin. We thoroughly enjoyed our stay.
