I stayed for a week for business.
My room was clean and silent, the wifi was provided for free.
During all the day you can take coffee, cappucino or tea for free in the lounge room.
The breakfast is quite good but maybe a bit expensive.
In front of the hotel there is the tram 1 to arrive to the center and 5 minutes walk (Lindspein) there is the bus (197) from the airport: the ticket costs only 4 Euros, very cheap.
I used to reach the center, Dam Square, by walking: it is about 25-30 minutes.
I suggest this hotel.
