The apartment has a good location in the old city. It is close to the center. Keep in mind a few things:
* Staining in the old house in the center normally means issues with heating. You have to be prepared with warm clothes as the temperature in the apartment feels colder than on the street (at least my feeling).
* I also had an issue with electricity, as it turned off a couple of times for me. But you can manually bring it back.
* In the bathroom ceiling height is lower, than in the rest of the flat (maybe up to 2 m). If you are tall - it might be not comfortable.
In summary, I believe this flat is a good choice in summer if you want to be close to the center and pubs area.
