First of all, I'd made a poor choice because I chose Insor Hotel which is open only until 8:00pm. Even though I paid for this hotel, I had to go and buy another one... Next day I arrived around 3:00pm and I tried to talk with receptionist but she did not speak any English. She spoke German but I don't. Fortunately, we were able communicate in Russian.
When I get to my room, the room looked like on the photo on the website. The room was fairly clean and specious. There was also a sink in that room. One thing that I don't understand at all is that there was no hot/warm water! Unbelievable... It is almost the center of Berlin, the capitol of Western country Germany, it was 2015 and there was ONLY cold water in my room...
I have to say that I chose this two stars hotel just because on Expedia.com it was stated that they have free parking lot. In fact, they don't provide free parking lot. They ask clients to park the car on the street next to hotel. It is free but it is extremely difficult to find a spot. Since it is for free, everyone wants to park there.
In conclusion, I don't recommend this hotel and next time, certainly, I will go to another hotel.
