Was in the appartment for a month in winter, 2 people. It has everything you need for a longer stay (kitchen has enough space for cooking, stove, oven, fridge with freezer, microvave etc., there is a closet, 2 desks, thermostat, bathroom and also a big terace). There are some essentials (vacum, towels, salt, hair dryer, kitchen towels,...). There is also a bath in the bathroom which I found very neat. Wifi was great.
Communication was quick, the owners are very nice and kind.
Lidl is right across the street, so is the tram station (tram goes every 5 min or so) and there are more grocery shops nearby. It takes around 15-20 minutes to get to the center (Schottentor).
There were some minor things like the radiators in bathroom not working but it didn't bother us since the appartment was warm either way so the hosts said they'd fix it after we left. No problem at all.
All in all, our stay in the appartment was great, 10/10 would stay there again.
