The flat has everything you need for a longer stay in Prague. We enjoyed the location, which was off the beaten track but within easy tram reach of sites like Prague Castle, the Brevnov Monastery (excellent food) and the Strahov Monastery (also good food and beer). Reaching the old town sites is a breeze as well. The flat is light, quiet and easily sleeps 3 adults. There's an elevator so you don't have to lug your bags up the stairs.
We really appreciated being able to do our laundry, as we packed light with only carryon luggage! The kitchen is small, but well kitted with microwave, coffeemaker (for 2), oven, 4-burner stove and a dishwasher. The pots and pans are sized for 2 persons; although it's totally possible to cook for more with a little juggling.
Communication was excellent and the host, very responsive and helpful.
