Dennis's place has an excellent location. You can walk easily to the main train station or the city center. His place is also close to a subway if you would rather use that instead. The place was also clean and spacious. One con was that the bed was quite uncomfortable. Another issue was that the door to the main apartment did not lock. The apartment is quite old and the door can easily be pushed open without using the key as the lock attached to the wall no longer holds the door in place. This was a bit concerning, but the building is passcode protected and the area is safe so everything ended up fine. However, I would still recommend that this gets fixed.
Overall, I would recommend Denis's place for a short weekend stay as the location is really great and its overall a good value.
