If you have any doubts about renting Arndt's place you can put them aside. The appartment is superb. Very pretty, very confortable, very clean and very well supplied with all the amenities one may need for a short or long stay.
The location is also very good. A great view, very calm neighbourhood but at the same time easy to come an go as public transportation is very close by.
Besides this the hosts are extremely charming and always ready to help in any possible way.
I highly recommend this place.
