Very good

Liked: Clean and comfortable
Disliked: The bathroom smells of sewage and the sink is really dirty and needs to be replaced.

Nice for a short-term stay...

Liked: The location is great - near the London Underground and easily accessible. Nearest bus stop is basically just few steps away, an indian restaurant is the next door and Tesco is right across the street. Staff was friendly and the place was nice overall. The room was below the ground level and had no window: I knew this while booking and it was totally ok. My bed was comfortable and the room was tidy. My room 017 was quiet during my stay and everything I needed was available there. AC worked well and the space was nicely warm upon arrival (in cold October).
Disliked: The sink drainage had clogging problems and the toilet drainage had water pressure problems.

Superb

Pleasant

Disliked: As were on 2nd floor and outside the window was a car park and night time lights from there were disturbing.

Superb

Liked: Easy to get from the hotel to Berlin city center with the train. Clean room, supermarket in the same building and restaurant with good Chinese food.
Disliked: It was always free parking, which is why I chose to stay there before. They (not the hotel, but garage) now charge for parking, which makes other hotels also an attractive alternative now.
