Everything was perfect. Communication with Jens ahead of my stay and even during the stay, as well as the (very late) check-in facilitated by Marco were great. Thanks so much to Marco for the bike-rental, too. Not only extremely helpful but also very kind. Much appreciated. Would not only recommending people staying there but would also go back in an instant. My trip was for business and being close to Potsdamer Platz was essential. Thanks so much.
