We've had a lovely time in this vacation apartment. The place looked exactly like in the pictures - nicely decorated with lots of sunlight. It was very clean and tidy, the bed was comfortable, and the kitchen was well stacked. Mauro's assistant dealt with any problems we had immediately, and in a friendly and accommodating fashion (for instance, I wrote her that the shower head was leaking - she answered two minutes later and about 4 hours after that it was changed, while we were still out in town).
It is however important to note that the apartment is not suitable for light or late sleepers - it's quite noisy at night, especially on the weekend, and the curtains don't block the light very well in the morning. Except that, please note there is no dryer but an electric drying rack for towels (like the kind you can usually find in hotel bathrooms). Also, the wifi doesn't work very well (we didn't mind it since we got local sim cards with a large data plan).
Other then these small issues, we enjoyed the apartment very much and would rent it again if we ever come back to Prague. I recommend it wholeheartedly.
