We spent three nights in the apartment and I can definitely recommend it for a city trip to Prague. It's only a short walk to the old town and the Palladium shopping mall.
Riad Jallou, the responsible guy for this apartment, had great tips for restaurants and sightseeing tours and helped us with everything. As we came to Prague by car, he offered us a private parking spot right in front of the apartment.
Only the gate and the entrance to the little parking lot were quite narrow... And if you are travelling with tall people (1,90m +), the bed could be a little short and the shower a little too low ;)
In total it was a pleasant stay and we really enjoyed our time in Prague.
