We've been spended 2 night and 3 days in Prague. And this apartmant is perfect in a perfect place. It's really about 2 minutes from Vencel square on foot, and from there you can reach everything easily.
First day we met with Alex, and he told us everything we need to know. It was very detailed and helpful.
The apartmant is cool and cosy, and exactly looks like in the pictures.
I can recommend Narnia for everyone calmly.
