The title about says it all. The Cortina is not beautiful, but it is excellent value for money. The service was unenthusiastic (and they don't speak English), but the bedding was surprisingly good, and the free hotel wireless was truly high-speed -- far better than I've ever found at a city-center business class hotel. The location on Kant Strasse in Charlottenburg is perfect: the S-bahn (Berlin elevated metro) is right around the corner and the neighborhood is full of restaurants of every ethnicity. There are also a fruit store and a small supermarket within one block (right on Kant as you exit the hotel, then across the street). In short, the hotel is a fabulous deal.
As with any super-budget hotel, there are problems. For many people the stairs will be an issue: you have to carry your bags up three flights of stairs. The reception desk is not 24 hour. There is a shared courtyard in which (during my stay) people from the neighboring building sat outside talking till 3 am Saturday night. Still, these are relatively minor, considering the price range of the hotel. I had no problems at all with bugs, dirt, plumbing, etc. Overall, I was very satisfied with my stay.
