Kilian was very helpful and responsive via WhatsApp.
We arrived very late after a flight delay and he stayed around to greet us at 11.30pm.
The apartment was nice and clean, we had two sets of keys which was VERY helpful. This is something that I wish everyone did, it gives you more freedom when travelling with friends, that you can split up and get into the apartment at different times.
Kilian provided two towels for each guest and the living room was spacious.
The apartment was a 10min walk from the Metro station in a nice quiet area with a balcony.
I enjoyed my stay there and would recommend the apartment to others.
