Andreas was very helpful and always reachable. e.g. alightbulb was out and was immediately replached.
the apartment is super nice and clean..the neighborhood is very close to coll districts, as it is in the centre the mainroom is loud if you leave the window open, but it' s big city ;-)
there is a supermarket near by so everything can be purchased for coffee etc. The metro is also really close. all in all we enjoyed our stay very much and would go there again.
