I rented this apartment for my wife's parents who are visiting from the US. Overall, the space was comfortable and everything went smoothly. However, the apartment was not very tidy when we arrived. I am aware that Heidi doesn't charge a cleaning fee and she expects guests to clean up before they check out. Of course, different guests will have different standards of cleanliness, so that can be a bit of a gamble. Other than that, everything was fine. The neighborhood is lovely, with easy access to buses and trams to all parts of the city.
