I stayed 10 days in Regina’s apartment in November 2022. The apartment is as large as described. Overall clean but I would not say perfect; dust could be easily found in some places and sheets and pillows where not so cleaned as well. The neighborhood is not the most appealing one, especially at night, but nothing weird or bad ever happened. Is located 5 mins (or less) from the underground of Margerentegurtel. The supermarket nearby was extremely useful.
The building is pretty old but the lift works fine and never had troubles with anyone.
In the end, I would say that, it has been a good staying.
