Me and my girlfriend came from America to go on a grand European tour. Our first City was Berlin where we stayed about 5 nights with Dirk. Anything that I would have to say about our stay with Dirk would be positive. He was very welcoming right off the bat- the elevator going to his 6th floor flat was broken, from the rain of the previous week and he helped us carry up our not so light luggage. He was just as friendly and helpful for the rest of the trip, very nice guy. For the room and apartment, again extremely positive and really was the cherry on top of our trip. Everything was very clean from the living room to the bathrooms. The view from the apartment is really nice and the location is EXCELLENT- I can't say this enough. Right near the Berlin Wall memorial as well as being right next to the tram and main train. It is just far enough away from the city center to not be too crazy either. Also very safe a night. There are tons of little shops where we were able to shop as well as get some amazing grub. Cannot recommend this enough, thank you Dirk for a great time!
(Also, the elevator was fixed the day after we left. So no need to worry about that.)
