Great location and Value.
Prague 1 is where you want to spend your time, and the train just down the street makes it easy to get to old town.
Full kitchen and good sized rooms. This is part of a Hostel so you will be sharing a bathroom. WiFi is poor, and does not work from your room.
For the price and location this is a good deal. You won’t want to hang out in your room, but why would you in such a fun city.
