I booked this hotel as I required a family room and was very impressed with it.
The room was huge and had the usual two singles pushed together plus a sofa bed, which had already been made up for us.
The hotel was easy to find thanks to previous reviewers giving excellent directions to it. It is only a block away from Frankfurter Allee on a street running adjacent to it but as the U bahn has different exits it could be confusing without a map or directions, as you would possibly exit the wrong side of the street.
The hotel was spotlessly clean and there is nothing that I could fault about it at all.
Breakfast was more than adequate with a very good selection.
We used the bar once, which we had to ourselves and the kids were able to surf the net whilst the parents enjoyed a beer.
I thought the 90 euros per night which we paid represented excellent value for money.

I wasn't quite sure about the hotel when I booked it. I booked it on the basis of the good reviews here and was impressed on arrival. The staff are good, breakfast is more than adequate, even though the breakfast area has the feel of a university canteen about it. The bar area is small but I never saw anyone using it during my stay.
The room I had overlooked the car park at the back of the hotel, it was comfortable and clean although would not have been suitable for a couple (twin beds toe to toe).
The hotel itself certainly stood out in the area, it's been renovated and looks a little out of place in a run down part of the old East Berlin. But the area is perfectly safe, and within easy reach of Samaritser Strasse U-bahn station.
Yes, there are hotels with a better location in relation to the city centre, but this is a good hotel and I would stay here again.

We had a short stay of 2 nights in this hotel and my wife and I were impressed. Large,clean room,substantial breakfast and a short walk to the underground and the quick connections to Alexanderplatz. Thoroughly recommended ,especially for slightly older guests,like us.
If coming from Schonefeld Airport, take the cheap regional express train-don't get on the S-Bahn,takes much longer and was suffering from disruptions because of trackwork

Stayed 3 nights in this excellant hotel,and thers no wonder thers good reviews about this hotel,its very clean,breakfast very good,and its in a good district with plenty of bars+resturants,also we found it safe to walk the streets at night time,and we where very late!!.I would have no hesitation in staying inthe agon frankfurter again when we return to this great city.
