Sebastian was extremely nice and helpful. The communication was flawless, the house was clean and even we can checked in earlier (at least left our bags). The apartment is at the ground floor which is a big plus if you have loads of luggage.
Sebastian also showed the surroundings which was a great hospitability.
We used bikes for the transportation and this is totally a recommended way of travel in Berlin.
Will love to stay ar Sebastian’s apartment next time around.
