Overall a nice stay.. We had our privacy, the place was clean, Ale was very friendly and the restaurant across the street was great, can recommend!
As previous reviews said, the ceiling is extremely low and I must have hit my head around 10 times in 2 days! A bath mat would have been good in the bathroom, and the soap was watered down and virtually empty. There was a kettle in the bedroom but no cups, 1 tea bag and a half empty bottle of German beer standing on the table, as if it were for the guests.. bit strange. These are little things that could be easily changed to make it great.
We chose the flat because we were driving and didn't want to drive into the centre, but it was equally stressful to find a parking place in the narrow 1 way street with impatient locals constantly at our bumper. In the end we had to park about 10 minutes away. If you're driving we'd recommend trying to arrive outside of rush hour and be prepared to drive in circles for a while!
As expected, it was a long journey to the centre.. during the day it was fine but coming back at night took 2 hours with a long wait at a sketchy bus station. I honestly wouldn't have felt safe as a single female traveller.
The price is great and you have a clean and private room and bathroom.. if you're willing to make the long journeys and leave with a few bumps on your head, you won't regret staying here :)
