Spent three nights at Arcotel Camino in March 2014 and had a very pleasant stay. We liked the location close to the train station and u-bahn station, though it was also an easy 20 minute walk to the city center. The rooms and bathroom were quite spacious and very clean with modern decor. When booking this hotel, the vegan menu options listed online appealed to me but we were never at the hotel for any meals in the end.
Staff was friendly and accommodating, and we enjoyed our brief stay overall!
