We had a lovely stay at Sören's appartment - it is a very spacious and above all a very clean place, which we find very important. The appartment looks very modern, has a great location (close to the city center and public transport-options) and is easy and safely accessible.
The only thing we weren't too happy about, was the noise in the early morning. When sleeping in the front-part of the appartment (by the street), you'd wake up around 5 AM every morning due to trucks supplying the Lidl that is next door (even with the windows closed). When sleeping in the back part of the appartment, you'd wake up from noise in the courtyard very early as well (maybe also from the Lidl). Sleeping with the windows closed during summer wasn't the best option either - it gets pretty warm inside the appartment.
Overall we would definitely recommend staying here because of the great location, the cleanliness and the comfortable space - but make sure you bring a pair of earplugs (or maybe you're not a light sleeper ;))
