Highly recommend!
The location is perfect, you can reach every famous Prague corner by foot, or basically take a train, which is just only 50 meters from the apartment.
The room is clean and huge as it is described. However, the ceiling lamps in bedroom and kitchen did not work, but you have standing lamps instead.
Jiri was great giving response within an hour. Although checkin procedures were sent out a bit late, but everything was perfect. You can use the entire apartment even after checkout
