The apartment is situated super close to the train station of Südkreuz which was great for getting into the centre of Berlin quickly and easily but it wasn't so great for the noise in the evenings. The apartment was quite cold even with the heating on but this is probably not so much of an issue in the summertime. Everything else was pleasant enough, the apartment had everything you would need for a stay in Berlin and the check in and out was perfect for us allowing plenty of flexibility.
