Check in was complicated by inaccurate instructions and a lack of cell coverage, so we could not access all resource information as we checked in. For the host's part their communication left out critical information to obtain the key. They also did not identify correctly which floor the unit was on. This made the check in about an hour. Otherwise the rating would have been better.
As for the unit, it was a truly interesting and unusual experience. The outer door to the building made you feel like you were entering a flop house. The hallways were also a bit stark. But, get past that and the unit itself was a fusion of old world and new. Someone very talented did some quality updates and then someone else followed with some finish work that was sub par. While this was surprising, it did not affect the overall experience. It may very well be that some updating is a current work in progress.
Overall, now knowing where it is and the check in essentials, I would rent again. It may well be a language barrier complicated things and a simple error on the instructions they sent led to the rough check in. Prague is a fantastic city and one sure way to dive deep is to be right down in the action. This apartment accomplishes that.
