All in all the flat is alright but there are several small things that can be easily optimized.
Negative:
First of all the water boiler (e.g. for warm water in the shower) made strange noises. During the night this made me wake up sometimes. Some things need to be fixed. The handle of the pan in the kitchen nearly fell off and also the tap in the kitchen was very loose. There were no basics in the kitchen like salt, pepper and oil. Annoying to buy stuff like this for only 2,5 days.
Check-Out time is stated as 11 am however while packing our stuff on the last day the cleaning staff was ringing at the door 5 min before 11. This was stressful as the woman was waiting outside the apartment already being disappointed. The next problem was that we had to take the keys out to get out of the parking area with our car (to open the gate). As this woman did not speak any English at all we had to explain why we still need the keys with gestures. Afterwards we brought the keys back up.
Positive:
Very clean and good connection to tram (but takes about 30 min to be in the city center).
