We spent a long weekend in Prague with the entire family (8 people from 2-70 years). Renata's apartment is beautiful, very spaceous and with a fantastic view over Prague. Location is also great. There are lots of retaurants close by and the city center is in walking distance.
Not all beds are back-friendly, especially the sleeping couches were rather uncomfortable. But the big beds were okay.
We can definitely recommend Renatas apartment to spend some time in Prague.
