I came to Prague with a friend from a conference as well as to enjoy some time off, the Narnia Flat was perfect for both. The location is super central, very close to the main train station and the Museum metro station, and you are walking distance to any touristic location. There are plenty or restaurant and bars around the flat, as well as supermarkets. The place is exactly as seen in the pictures.
The Ruterra team was very responsive and attentive to our needs, having their offices close by is definitely a big plus in case you need anything like we did.
