Great apartment, very big, clean and comfortable.
The location is awesome, very close to Charles Bridge but a little outside of the main road so the street itself is not crowded. Just 5 minutes walk to a metro/tram station. The cafe downstairs can be noisy during the day (it closes at 22 so not a problem at night).
The communication with Jaroslav was great and he responded to quickly to any question/request we had.
