Quite simply, I would highly recommend this place!
To give a bit more detail: the apartment is actually bigger then the photos show; the apartment is beautifully laid out with modern and high quality finishes; we cooked dinner every night and the kitchen had everything you needed (Slavo had heaps of supplies in the fridge and cupboard you can use as well); living area has a comfortable L-shape couch with a large apple computer that can be used as a computer or a TV; the bedroom is walled off with a bi-fold door over a bench which is ideal as you can swing the TV around and watch it in bed; the bathroom is perfect - great shower head. There was a balcony also with massive windows which provide great lighting.
Now onto Slavo: great host with an interest in looking after his guests; always gave advice on what to see and do in Prague; provided tram tickets for us and guided us to which line to catch the tram into the old town; was very quick to reply to emails; he met us at where we got dropped off and helped carry our luggage to his place and even helped us carry our luggage back when we left. I cannot fault him or his apartment. Only thing I would add to the apartment is a washing machine if it could fit, but definitely not a deal breaker. Thanks Slavo.
