The flat itself was very nice. It has everything you need and there's a bus stop right outside the door, so getting into the city center is no problem. The street is pretty busy and it can get a bit loud with the windows open but I personally wasn't really bothered. There's lots of stores close to the flat (most important ones being Billa and Lidl) but also restaurants and a park right behind the building that is fantastic for runs or watching the sunset.
I already miss Prague and can only recommed Irena's flat :)
