Very nice and big apartment, perfect for a family or a group of friends. I rented it for my family coming to visit and it was great. Comfortable and with all the basic needs covered, even a dishwasher. Even though it's right above a café/restaurant and nearby few others, with the balcony closed you don't hear any outside noise which is great.
The location is also very good and central.
I can definitely recommend it to spend a few days in Prague.
The communication with the host was fast and easy, everything was smooth.
