i would highly recommend Katerina's place. The location of her place is perfect for all the tourist spots and also there's a lot of restaurants and establishments close to the area. Katerina is such a very nice and sweet host. She made sure that out stay will be pleasant. She responds quickly on our messages. I've been travelling a lot and use to stay on airbnb's but she is the most sweetest host i ever encountered :) and her place is so perfect. i will definitely stay on her place if i travel in Prague in the future :)
