This is a fantastic place to stay! Our group had four adults and four children (all 5 and under) and this apartment was perfect. There was plenty of space, lots of bedrooms and bathrooms, and a lot of play space in the dining room/kitchen and hallway area. The apartment itself is very clean, with lovely high-ceilinged rooms. It's in a great location - right next to the National Museum, you can walk pretty much anywhere, and right next to a subway station. Despite all this it's very quiet inside. Our host was very communicative, keeping in touch and organizing a taxi with car seats for our transfer from the airport, and it didn't matter that our flight was an hour late. I would highly recommend this as somewhere to stay in Prague!
