Nice, clean, well-located apartment. Some 40 min., away from city centre by foot - close to the metro, however - but gives opportunity to traverse and see the city more (if you are that kind of tourist, I am and appreciated it). You get a good feel for the non-touristic places of the city and might feel more like a citizen than a tourist.
Stefan & Teo are fast to reply and super nice and helpful. Highly recommend this apartment.
