We spent three days in the apartment and enjoyed it there very much. The way to the apartment is very easy to reach from the main station with line 23! The location is very nicely situated! Directly above is a nice bar, which we have visited twice and can also highly recommend! This has been heard in the evening very quietly, but this was absolutely not disturbing! Mostly just nice music was playing :)
We can recommend the apartment for all who do not want to live in a typical tourist location. In 15 minutes you are down in the city center. Up in the old town are very many nice small local restaurants, which we can also recommend!
