Positive points about this flat: nice, clean and well equiped, Ivana answered very fast to the messages.
Negative points: far from the center but next to the subway station + the flat was cheap.
If you're a heavy sleeper this flat won't be a problem, indeed the walls are pretty thin thus you can hear the tram passing by. For those who are more sensities I wouldn't recommand it. As a heavy sleeper it wasn't a problem.
