Considering you are in the center of Prague, you can't hear a single thing from the busy street. The place is really pretty, quiet, nice place to chill after a long working day. I had no issues whatsoever, it was only just a tiny bit difficult to find for me personally. I was met by Zsofia's friend and he was very nice to me as well, communication was very clear and her friend answered all of my questions with ease. Would recommend!
