This is a great apartment with almost everything you'll need in one of the best neighborhoods of Prague, across the street from a gorgeous park and within a few minutes walk of a supermarket, lots of mini markets, and great restaurants and bars. Also an easy 30ish minute walk or much quicker tram ride to most of the sights in the city. But definitely spend time exploring the neighborhood itself too.
Pros:
Amazing location
Well-equipped apartment
Excellent communication from the host
Cons:
Could be a little cleaner (some dust bunnies, trash left in the bin), but not too bad
Entrance a little difficult to figure out, but only the first time
A couple maintenance issues (broken and loose floor tiles) but they didn't really affect my stay
I spent two weeks here and, overall, I can recommend this apartment for a great stay!
