We really enjoyed our stay in the apartment. The location of the apartment is awesome and everything is in walkable distance if you are good by foot. If not the railway is in front of the building and you can take very cheap the tram wherever you want. As example the 22 line is going straight to prague castle in 15min.
Around there is everything you need. parking Garage, supermarket, ATM, Kebap, a lot of bars etc. You will have there everything you need to enjoy your visit.
The apartment is just great and also super to stay there with your family.
