Roi is the perfect host, prepossessing, full of good things like give a map of Berlin very helpful throughout the stay! Regarding the apartment, it is simply sublime, it feels like home, super comfortable, we rarely slept so well, in absolute quiet. The presence of the AppleTV is really good surprise when you have a macbook to hang between two outputs and watch a great series.
Very easy to communicate with Roi, for advice on transportation, call a taxi when our German is bad.
Thank you for everything. If we return to Berlin, we will definitely stay at this apartment !
