Arnd's is conveniently located near the central train station (not the central bus station, which Arnd thankfully corrected us about). We were able to walk with our packs to the flat without any difficulty. There are very cute and quite restaurants just a few blocks away from the flat and Tier Garten is a short walk away.
Everything felt very clean and Arnd was kind enough to provide basic amenities, as well as tea and coffee. He readliy answered all of our questions and had a binder full of information on tours and public transit that was much appreciated when planning our day. Thank you, Arnd!
