Monika is absolutely amazing host!
Apartment has everyrhing that you may need and even more. It's very comfortable for two persons. All my stay I felt my self like home, super safety, super quiet street.
Nearest metro/subway was in 5 minutes by foot.
Only 20 minutes by foot to the Prague Astronomical Clock (old city center).
Just 15 minutes by foot and you're at Main Train Staition. Super comfortable for people who travel in (or leaving) Prague by train and for those who would like to visit another city for 1 day trip (as example Dresden).
I highly recommend this apartment to everyone!
