VERY NICE place to stay. The apartment is exactly as pictured, it's really beautiful inside and very large and spacious.
The location is amazing, in the very centre and just a few minutes walk to the Old Town Square, and less than 10 to Charles Bridge.
From the Windows you can look down to the main busy streets. The apartment is 4th floor without an elevator but that was ok for us. I can highly recommend for a beautiful and central place to stay in Prague.
