I stayed with some collegues of mine at the appartment. The appartment is really nice and has everything you need. Rooms are big and bed are really comfy. The majority of rooms in the appartment is facing the street side, which is quite busy. Sleeping with earplugs recommened, especially when you are not used to noisy streets. There is one room facing the backside, which is a bit less noisy. The hosts always responded very quickly within minutes, which made the stay even more comfortable in case there was a problem. Its close to the main station (10 minute walk) and you can walk to the ancient city center very easily with 15-20 minutes! All in all, we liked staying in the apartment and recommend it!
