We were 6 days in Prague and the appartment is ideal situated near the Wenceslas Square (60 meters off square) in the centre of Prague.
Very nice and clean appartment with large kitchen, 3 separate bedrooms, 2 bathrooms.
Rooms were clean and extra pillow, blankets available if needed. More towels is preferred, but washing machines can do the trick.
Because we were with 5 an extra spare set of keys were given to us.

Neighbourhood is noisy, so sleeping with windows open is not advised. Also curtains should be thicker for a pleasant night sleep.

We did not have to check out and could leave the keys in the apparatment. This saves a lot of time.

If you have a lot of Luggage, as we did, take a taxi because this makes live a lot easier.
