We stayed at Zuzanas Apartment for 4 nights and had a great stay! The place is really central and close to a lot of sights and restaurants. We spent the whole trip only walking around prague which was only possible due to the perfect location. The place was clean as well and we felt very comfortable. We got send a pdf with a lot of information beforehand which helped with where to get the apartment key or gave some other information about things to do, this was really helpful.
There were some renovation works right outside the window in the courtyard of the building, which could get a little loud from around 8 or 9 am but that just got us out the bed at a good time to see a lot of the city :)
All in all, a great place to stay!
