The flat is nice as well, it looks cozy and modern. It contains all the facilities apart from vacuum cleaner. Although it faces the street, I never heard any noise from there so the isolation is good. During colder days I could always set up the heating so that it was warm enough inside.
The location could not be better, metro and trams (+night route) are around the corner and Karlín itself is a clean and silent district very close to the city center at the same time.
The studio is in a great location, everything you need is near by. All the best recommendations to this place.
