Great place to stay for even several days trip - comfortable, near public transport station and not so far from city center even by foot if you're in mood for a longer walk. Everything necessary was provided, and we even got additional stuff - we asked if iron is provided and even though it wasn't by default, Walther delivered it to apartment before our arrival. I must add here, that communication was perfect - fast, clear and nice. The check-in method is very simple and comfortable - come, pick keys using given code and you're in - no worries if your transport would get late or sth else happen. I definitely recommend staying at Walther's place. :)
