Great location! The neighbourhood is really nice. There's supermarket right around the corner, a park and some lovely bars & restaurants.
The place is very clean and the size of the appartement is perfect for a few days and nights in Prague. Don't forget to bring your own shampoo etc., it's not available in the appartment ;)
We were especially really happy with the lockers outside of the apartment, which we used to store our luggage after checkout. Very convenient if you have a late night flight, but still want to explore the city.
