When it comes to location, the place is great. You can easily find you way into the city and nice restaurants and coffee shops. So thats a plus. It also has been clean when my friend and I arrived. Christian and Jang are also very nice and communicative.
Still there were a lot of unexpected issues coming up, which I only mention here since I am a host myself and have several experiences traveling with Airbnb.
The description of the flat and what the hosts offer aren't quite right. There is no access to the kitchen for example. Also they are asking for a cleaning fee (in our case 32 Euro for 2 nights) but when you arrive you see a set of rules that tell you to clean the toilet/mirror/bathroom floor after using it. Since they rent out 2 rooms via Airbnb, not just one, there are (incl. the hosts) 6 People in a small apartment sharing one bathroom. There are signs all over telling the guests what to do and what not to do. They also list the fines you have to pay for not removing make-up before going to bed since you might leave stains on the pillow. So as other guests stated before, those signs and rules make us feel uncomfortable. The walls are thin, so you will hear every word of the other guests, so I advise you to bring earplugs. There is always a smell of Asian food in the place, at times it was ok, at times it was disgusting. When we mentioned it, the hosts didnt understand, but offered free storage of our luggage.
If you look for a nice location, you can stay in one of the rooms. If you need the feeling of being yourself, laugh and talk a lot and have problems with certain smells, you better stay somewhere else (there is also a sign that tells you to not make phone calls in the rooms...)
