Good location, modern and new spacious apartment. Very much appreciated that we could park in the garage and not worry about the car in some public parking.
What we lacked was some 'personal touch' in the apartment, no coffee/tea, no soap for example. This probably is not a problem for many people, but I like to feel welcome when traveling via airbnb.
No mattress in the baby crib so bring your travel one in case you are with a kid. Watch for little bugs that come out at night in the bathroom and hall, hopefully this will be resolved soon. Overall, I believe you can rent cozier places in Prague, we were limited by location.
