I very much enjoyed my stay at Josef's appartment! Everything was super easy and accommodating (check in, communication before and during my stay, check out). The flat is great (very clean!, bright, comfortable bed, nice bathroom etc.), good location, right in the old part of town. The area is quite touristy, you enter the building through a souvenir shop (didn't get that when booking) but it was quite fun, actually. Not super quiet at night but with the window closed it's perfect (and I'm a light sleeper). So all in all: perfect place if you wanna be in the middle of Prague!
