I am sorry that Aaron did not enjoy his stay in Belgrade. It appears that he was staying in Belgrade for the first time, and is just one of those people who is vey difficult to please. Regarding the Air Conditioning in the apartment, it does have a top notch AC unit that can cool the entire apartment in a couple minutes now. The apartment was completely renovated in January 2017 and everything is brand new. All of our previous guests loved this modern apartment, as you can see from the reviews. We are aware that Belgrade can be hot in the Summer, so just prior to Aaron's arrival, I had scheduled an AC unit to be installed. The installation had to be postponed because Aaron did an instant-booking, and arrived at the apartment shortly after booking. We accommodated Aaron as much as possible, but I guess it is true that you can't please everyone. I wish Aaron peace in life. I hope that anyone reading this will see past Aaron's snippy comments and will enjoy their stay at the fully air-conditioned Four Bridges View when they are in Belgrade.
