The hosts gave a lot of information, and a lot of useful advice. Check-in was a breeze, apartment was clean, and just like the pictures. Neighborhood couldn't have been better: very close to the center, close to tram/subway, close to places to eat, shop, etc. The apartment building was very secure as well. I'm absolutely satisfied, and from now on will try to only rent from Olga and Emil when I go back to Prague.
