To start with, the pictures of the apartment on the AirBNB site are NOT pictures of the actual apartment but a collection of pictures of other apartments in the same building. We were in apt 25 while we think almost all pictures are from apt 26 (according to the website of the building). You could call this "confusing", though some might come up with other terms.
The apartment wasn't really clean. In the bathroom there is fungus on walls and ceiling and every day we had to catch some rather large insects in there as well. The coffee filter of the previous tenant was still in the machine. No need to explain what it looked like.
One in two light bulbs were working. Several power sockets didn't work. Some of them weren't even covered. So, beware with small children.
The sink in the bathroom didn't work. It took almost half an hour for the water to drain.
It was hot, but I can't blame the host for that. But the broken ventilator is his responsibility. Because of the heat we slept with open windows. Not a good idea. At 3am, almost every day, drunken tourists are strolling the streets singing all kinds of cheerful, but worthless, songs.
And when they all have fallen asleep, there is the collector of empty bottles. Again, the host is not to blame for this daily 6am act that awakens the entire neighbourhood, but unless you are part of the 3am herd, this is not what you are waiting for. But hey, I succeeded in sleeping 3 hours every night between 3am and 6am.
In the end, if you want to be part of the herd, and if you want to stay close to the action (I was told the rooftop bars are awesome), and if you want to sleep in till lunch next day, this is a good apartment. Otherwise, steer away from this.
