Easy booking, fast communication responses, easy check-in and the apartment is lovely. As a personal touch - they printed my Airbnb profile photo and had it in a frame in the apartment! They provided lots of recommendations for restaurants (loved Cafe Nest!!). This apartment is in the city, so be prepared for some street noise, but it’s not anything unexpected. And the location is great, 5 minute walk to Nachsmarkt and also to Karlsplatz for the U.
