The hotel is average, of the advantages - it is located not far from Alexanderplatz, you can walk, good air conditioning in the room, and quite decent breakfasts. Among the disadvantages is a very small room without any special frills, without a safe, with good audibility, several shelves instead of a closet, with a small bathroom, but I don't think you should expect much from Ibises. The hotel will do for a couple of nights, but next time we will not settle here.
I really like the Ibis network, it's not the first time I've stayed. Nice and friendly staff, beautiful rooms with a "super" comfortable mattress (I get high every time), hearty breakfasts. The location of the hotel is good, the center is just around the corner.
I haven't found any disadvantages yet.
A wonderful hotel! The staff, the environment, everything is fine! The only drawback is that there are no dishes and a kettle with boiling water in the room, I had to go to the bar on the first floor to get boiling water. And so everything is wonderful!!!
