We've stayed here for almost two months at the end of the year 2022. The location is very quiet in winter, probably a bit louder in summer if you want to have windows open because there's right next door. The temperature in the apartment was also very good. Overall we really liked our stay, it was a great value for money. Location was very good, there's a park nearby and a lot of cool restaurants around. It's easy to get to the center by public transport but we usually walked (about 15 minutes to Wenceslas Square). I would recommend this place to anyone who wants to stay in Prague.
Not everything was absolutely great though - the bed was really bad and also quite dangerous because of very poor quality grid. Also, due to a forgotten update request we had to leave for one night in the middle of our stay (we wanted to extend our stay and it was forgotten) which was a bit inconvenient and also there was some accident which resulted in not having warm water about half of the day.
