The flat is perfectly located: it is in a quiet neighborhood, but near to the city centre, everything is at a walking distance from there. The apartment is big for two and it has got all the stuff you may need.
Michal is willing to arrange the check-in time depending on your necessities and the communication has been great.
I would suggest the flat to anyone who wants to enjoy the centre of Prague without using public transports and desires some peace during the night.
