This hotel is good for people travelling on a budget. It's cheap. In every aspect.
The rooms a big enough and the bathroom is well kept, but that's about it. The beds are very bad, my back did not like them. If you want to use an electric charger for your computer or phone, check the wall socket before you plug it in, it can fall apart. The reception on the TV is awful, some channels are useless because of it.
So, is there anything good about it? Yes, as I said, it's cheap, also, the staff is very friendly and helpful and the breakfast is not bad. It's also very close to U-Bahn and a very good italian restaurant is just 50 meters away. Within 20 minutes walk there are many more excellent restaurants and also Checkpoint Charlie, if you are interested.
So, if you are on a budget, by all means stay here, but for just a little bit more money you can get a much better hotel.
