The apartment is in a great location and Zeb and Josef were great in their communication. I came to Prague by train but due to a delayed train I arrived to the apartment about 2,5 hours later than originally planned. This wasn't an issue at all.
However, it was a bummer that I didn't get to take a hot shower at all. There was supposed to be hot water (only) twice a day, but by 8am the hot water had already run out. Now that was a little less of an issue in a heat wave, but still not very pleasant. There was also mold in the shower and the apartment was not very clean. Also, the apartment is above the coffee shop and it could get quite noisy at times. With the windows closed it didn't bother me anymore.
