This is an okay apartment with a reasonable distance to the convention center (15min walk). The owner was not responding to my questions and only sending me prewritten messages, I hope that will improve in the future. The flooring in the apartment could also use some improvement since I encountered some loose nails which tore my socks (fortunately, they were not sharp enough to injure).
Overall this was an okay apartment for the money. Something like 3,6 stars, not great, not terrible.
