The apartment was advertised as having Wifi. This was very important to us and one of the reasons why we chose this airbnb. We had an important video call scheduled during our stay and it was not possible because the wifi kept dropping out. It wouldn't let our laptops join at all. We reached out to the host, they suggested we log into another wifi and maybe would send a technician. It was never fixed. The host didn't treat this as a very serious issue. An important appointment was lost as a result. We couldn't use mobile data in the apartment as it was 3G with barely any signal. Enough for a voice call but it kept dropping out.
The electronic lock for the door froze, and prevented us from entering the code. If we had not been able to contact the host, we would have been locked out completely. No one can be contactable 24 hours a day. The door has a 9 digit code which is unnecessarily long. It's really inconvenient to enter a code that long each time you enter the apartment. The English instruction for the "child lock" is incorrect. We noticed reviews written by other guests complaining they were locked INSIDE the apartment. We were also locked inside for a while until we figured out how the child lock worked. No thanks to the instructions. Being locked inside an apartment seems pretty dangerous in the event of an emergency. The English instructions for the child lock tells you to "push top of button" when it should say "slide". (For example an iPhone tells you to "SLIDE to turn off" not "push to turn off.)
The first night we stayed the apartment was very hot. The air conditioner would run for one hour and turn off. This meant we had to get up every hour to reactivate it because the room was so hot. The room was still at 25 degrees by morning. Very unpleasant with no outside window. The next day we figured out the system was set for a 1 hour sleep timer. Either way, the air conditioner should really have been on before we got there, to have the room nice and cool in such hot weather.
When it came to cleanliness, we found a soy sauce container stuck between the wall and the bed. It had stained the white curtain. Also some dishes were dirty, including a big lipstick stain on a coffee cup. It became clear that a thorough clean had not been done. Please note, the window does not get any natural light as it doesn't actually open to outside. It opens out to some sort of atrium with a small amount of light and air coming from 3 floors above. The photos of the listing hide this well.
Good points, the apartment is very close to the metro so transport is really easy. There is also a really good bakery on the corner (so good, seriously). The street is really quiet and the area is quite nice as well. There is plenty of places to eat and supermarkets very close as well.
To be fair, the host was very responsive to our messages. When we were locked out due to the keypad failure of the door lock, they called us within one minute.
