I didn't formally meet our host, however the apartment was beautiful. Really good location on the river with great views.
Spacious rooms and clean modern facilities. Definitely would recommend if you're a big party (there was enough room for 10 girls!)

For prague in general, it is a beautiful city and there is plenty to see over 3 days. If you get taxis make sure you decide a price and don't trust the meter in the cars!! They are very unreliable and can be very expensive for the distance you need to travel.
