We had a perfect stay in Hubert's flat. Communication was seamless end to end, Hubert is very flexible and check-in & out were perfect. The flat is great, perfectly located in front of a subway station. Very easy to reach from the airport and a couple of stops from many places to visit in Berlin. The flat itself is perfectly quiet (on Friday evening, neighbours may not be, but that's fine :-) ). There is a very large living room, and 2 rooms also very very large. Bathroom is perfect, and everything is 100% clean. What else can I say ? Thank you Hubert !
