We had a great stay with Sona! She is very flexible with check-in time (she stayed up until our flight got in at 2AM to show us to our space/give us a few tips on navigating the tram system). She also leaves out snacks and some food, which is very considerate. The space is tidy and cute with a lot of nice, natural lighting. There's hot water and good wifi, too.
The only downside is that it take awhile to get into the city to see any tourist spots. I'd say it took us 40-50 minutes to get to the Old Town or Charles Bridge. The area is sort of rundown and not anything to look at, but the actual living space you stay in is very nice.
Overall, I would recommend this Airbnb to a friend if they were looking for a place to stay in Prague. Definitely worth what you pay!
