This apartment is not what it looks like on AirBNB. It is absolutely unsuitable for 4 guests. Basically it has only one bedroom, so a couple could stay there for longer, if they use one bedroom.
Two colleagues however, who need two bedrooms, might be happy for a night or two, but for longer? Never.
The one bedroom is tiny and would never allow two people. It has no windows and one wall is made of milk glass. It has a sliding door as entrance, that you can not lock. Opposite the the milk glass wall and sliding door is the kitchen. So whoever sleeps in this so called bedroom, will be woken up every morning as soon as the other person needs the kitchen.
You will be given only one key. And to get a second one....let's just say Paul and Dan have been more difficult than necessary. Without the key and the FOB, you won't be able to enter the building and if there two people sharing one apartment, you need a second key. Now to get that second key.....well, climbing the Mount Everest is easier.
