Milena's flat is a modern gem in the centre of Prague. Almost everything is within walking distance, and those sights that are not can be very easily reached with the various means of transport. The subway station is nearby, too.
The building is incredibly easy to find and the check-in procedure is worth 5 stars alone. All the receptionists are friendly and speak English. As to the flat, it contains all that's needed for your stay in Prague, it's clean, the beds and sofa are comfortable, and the bathroom is quite big for a flat in this metropolitan city. The flat is exactly as advertised by Milena.
We loved our stay there to bits!
