This place is great!
Recently renovated, newly equipped cosy flat on the 5th floor (with lift). Exposed to the patio, with no noise from outside, however the nearby is also very calm itself.

It is located 6 metro stops from main railway station (10 minutes ride) and 2 stops from downtown.
Most of attractions are accessible by foot, Hradcany Castle in 25 minutes, Charles Bridge in 30 minutes.
Also famous tram 22 can be reached in 15 minutes by foot.

Did I mentioned flexible check-in and check-out hours? They are another big advantages too.

And finally Jiri and Kate are warm people, very helpful and open to any suggestion.
I definitely recommend stay at their place, I will definitely do, when I am in Prague again!
