Absolutely worth every penny. One of the best apartments we have stayed in with Airbnb. Much larger than it looks on the photo due to high ceilings. We traveled with our 5 month old baby for 4 nights and it was her first international trip and this apartment had everything we needed to make the stay pleasant.
Location, Value, Host communication, Amenities, Size, Sound insulation, everything gets a high score. If you are considering this apt for your stay in Prague and it is available, don’t even think about it, just book it. You can’t go wrong with it.
