We really enjoyed our stay in this appartment. You should be aware there is a tram track nearby with fairly regular service. You will be able to hear this as it passes by. There is a bar below the apartment but we never heard any noise from there. The apartment is in a generally quiet street but with trams busses and metro all within easy reach. The no 23 tram is just around the corner. There are shops ,bars ,restuarants and cafes all just round the corner as well as a laundrette which we found useful.
I would recommend this place for a stay. It's a great base from which to explore prague . Romana was able to answer all my queries and was very helpful.
