Me and my 4 friends had a really good experience with this apartment! In the city centre, great interior, awesome sound system (even in the bathrooms) and everything you need is already present (towels included). Andreas is a good host and did his best to make our stay as comfortable as possible!
Small tip: bring earplugs for the night because there can be some street noise. We all brought earplugs and slept right through it, but I can imagine that this could cause some problems if you don't use plugs.
