The place is very nice for this budget and David and Lenka are so nice and welcoming !
Even if the sight is not terrific (on an urban exchanger), it is well located to get to any place in Prague (even more than old district or so) because of the central railway station and tramway lines nearby.
There is also a nice park just outside that is a very vivid testimony of the actual city life of the inhabitants.
At last, some transportation's infra bass might bother you if you are sensitive, otherwise the flat is very well acoustically isolated.
Good luck to David and Lenka for putting up this place, see you !
