It was very easy to communicate with Duc Son, he was flexible on early check-in and early check-out. The flat was just as in the pictures, clean and equipped with all the necessities. Location of the apartment is good, right on Prenzlauer Allee, tram stop is a minute, several cafes and restaurants in 5 mins walking distance. Windows are looking to the inside courtyard of the building so noise level is not disturbing.
All in all, we had a great stay in Berlin, thanks for hosting!
